Sister went nuts over a cup of coffee

In a restaurant a lot of coffees do come filled right to the brim but agree in a home people usually leave a small gap so as not to spill. It depends how much of a gap you’re leaving though. I have a friend who we jokingly say only fills half cups of tea/ coffee; in reality she is probably filling the cup up to between 2/3 and 3/4 but is still leaving far more of a cup than necessary. Assuming you have a steady hand then you only need to leave half a cm to a cm or so, that’s more than enough space for unless you are running with the coffee!

That looks like murky water, not tea or coffee.

Almost to the top yes
Half a cup full no

let Her pour the water herself

Not yet, but if it meant I got a proper cup of coffee the next time I'd give it a go.

Surely you’re weighing the coffee beans and water anyway so the brewing ratio is correct? You wouldn’t be able to just fill the cup up after the coffee has brewed because you’d need to grind more coffee

I don't drink coffee but also don't particularly like a cup of tea where there's too little in it. Don't ask me why, but it's wrong.

I think we need the OP to give us an honest photo of her coffee based offerings.

Yeah but do you dance around yelling and shouting "oooh don't spill it" in their face?!
She sounds deranged.

Your sister and husband are both very rude and I wouldn't be keen on having her round to my house again in a hurry.

In answer to your other question though, yes, it is normal to fill cups and mugs up close to the top. I get annoyed if presented with half a cup of tea or coffee. I like it filled to half to 1 cm below the rim of the cup/mug. I wouldn't be so rude as to say anything to the person hosting me who had made it though. I'd keep it to myself because it really doesn't matter that much as a one-off.

Molehills and mountains come to mind.

I like a nice full mug myself, but it's beside the point really. What's very much to the point is your sister's atrocious behaviour and the way your DH took her side. My DH is a teddy-bear, but if my sister treated me like that under my own roof, her bottom would hit the pavement before you could say "one lump or two?"

I'm a bit on the fence with this and think you are both being unreasonable. I drink black coffee and it makes me sad when someone gives me a "short" cup because they take milk and I don't and they leave the same milk margin. I fill my mugs up to about half a centimetre from the top of the cup. If I had had a comment from a guest that my measures were short, I'd make sure I gave them a full cup next time. Never mind every time, three times a week! I think that might give me a tiny bit of the rage. So you are being unreasonable to continue to not give her a full cup. Unless there's a drip feed coming that if you fill her cup more than half full, she spills it everywhere.

On the other hand, she seems a bit crackers to go so over the top about it, she could just go and fill her cup up a bit more after rolling her eyes at you. Is she prone to crazy behaviour over small things or could she be thinking you are now doing this on purpose and it has tipped her over the edge?

Complete no need drama, put the coffee jar, spoon, mug, milk by the kettle and tell her to make her own- sorted

Can you elaborate in the weirdest part of the post (as if the first half isnt enough) which is this bit

DH witnessed all this and basically joined in with her.

If it were me it would be a non issue as she wouldn't be back in my house.

Equally with my husband I wouldn't make him tea / any drinks or cook or wash anything for him for the foreseeable.
I'd want to grovelling apology and a big "sorry im a DH" (dickhead) present before any kind of normal service resumed

The thing here is your husband agrees with her, which makes me think you’re under filling it and it’s one of those things that grates on them noth.

Was it mellow Birds?

Agree! It's not really about the coffee, is it?

Gosh, what immature dickish behaviour!
I can’t believe I’ve even read this! 🙈

She sounds utterly mad, but also is your sister. Sometimes, no matter what age, you can fall back into being 6 years old and behaving like a child when you’re with a sibling. It does sounds very very odd though, but I guess she’s just snapped at this weird coffee situation.

I think what matters is how she usually is and how she behaves over other things? Is she generally mad/unhinged/unreasonable?

Your husband has no excuse though, to join in with sibling nonsense.

But also… could you make a coffee and show us a photo of how you make them? Enquiring minds want to know!

Your DH joined in with her? Mine would have thrown her out of the door.

Never mind not making a coffee for her anymore she wouldn't be coming into my house again, she can make all the full cups of coffee of the brand she wants in her own home.

Just stop making her coffee and let her make her own. Not a big deal.

I would never offer her a drink again. Problem solved.

(For the record I used to joke with colleagues who only gave me 3/4 of a cup of tea because they left space to put milk in but I don't take milk, but only to the extent of saying 'can I have a whole cup please?' and I'd top it up myself.)

As was I - who knew hot drink entitlement was a thing? But turns out it is!

I say that sitting here drinking a warm-ish cup of ginger tea because my lovely mam went to make me one and forgot the kettle had boiled because she was distracted by the cat. So I have a warm-ish cup of ginger tea - it's not horrible and if I wanted to top it up with hot water then I can get off my bum and do it.

Well I dont know to be honest.

I admit to having a bit of a fit at OH once because he fills things right to the brim, I mean right to the brim, he does it with everything and I wince when I see him doing this because he is incredibly clumsy anwyay

But, I have a disability in my hands, so I must have things filled quite low down, half a cup, perhaps just a smidge more. And he never remembered or bothered to do this so each bloody glass of something or cup of something I couldnt touch because instant spillage. And I snapped one time and had a massive go. Im sure I would have been seen that day as unhinged.

Obviously the context is completely different here, but sometimes we have our limits.

The unfilled cups sound annoying, and as an adult, I would be really irritated by the suggestion that I couldn't have a full cup because I might spill it. So I understand her annoyance.

But her reaction was fucking stupid, regardless of how full the cups were. Total overreaction and unacceptable behaviour on her part.

I wouldn't want her coming round again.

Christ don’t come here, big mugs as I leave a significant gap. They can have as much as they want!
She sounds insane. Are you a clean freak op? Either way she was rude.
