AIBU about my friend never saying thank you?

[ValiantMouse]

I met up with a friend the other day and we went for brunch. I paid and said friend never said thanks or anything like it. She's just moved into a new house so rather than buying her stuff before the house is organised, I baked her and her DP a cake and gave it to them with a bottle of wine. She took both and never said a peep again. I kinds shrugged it off and figured maybe she'd sent me a text when she'd tried it and say thanks then. It's been almost a week and she still hasn't been in touch. I'm a bit upset- I worked hard to make a nice cake and feel like it wasn't appreciated!

It's not just these few times- it's happened in the past too. AIBU?

I'd stop doing anything like this. It's damn right rude. Did she just take it from your hand without a word? I can't get my head around that, someone hands you something, you say thank you, it's a no brainer!

How very odd!? Did she say anything at all? While taking them I mean?

Oh fuck that. I cannot stand this especially in grown adults, bloody rude. I find a "you're welcome..." usually gets me a thanks, I don't give a crap if its a forced one

She just took the bag from me.

You paid for brunch then gave her a cake and wine? No thanks?

Bloody rude cow. I'd have to say something.

Does she ever pay for you? Or give you gifts?

Bloody rude cah! I can't abide bad manners

I find this is an eldest child trait. They are never the first to say hello and 50% never say thank you. Just a small study over a 10 year period. Is she the eldest?

We take turns to pay and she gives me gifts for big occasions. Just never says thank you!

Never pay by card. Always pay by cash, and in this situation just chuck down the cost of your meal (or 50% of the bill, depending on how generous you're feeling). Simply don't let this happen.

If you take turns to pay for meals then her not saying thanks is maybe just an oversight as it not something she should feel especially grateful for, given that it's a two-way arrangement.
The wine and cake thing is just weird, to take a bag without acknowledging what's inside with a thanks is just wrong.
