Friend bought doubles when I asked for singles

There isn't a Scottish/English divide on this. Any pub can sell in multiples of 25ml or multiples if 35ml they just can't sell both.

35ml is becoming increasingly common everywhere

If it's in front of me, I'll end up drinking it. I only throw away when it's a repeat offence.

I don’t really understand why she specifically asked you single or double if she was just going to buy doubles anyway. However, I think she possibly didn’t think it through and thought she was being generous. I’d make it clear to her that next time if you ask for a single then that’s what you want - I wouldn’t fall out over it.

im sure they don’t… bit unnecessary don’t you think? You could always just not drink all of it…

"Even if I thought the drinks were singles, when I start to feel drunk I could choose to move to a soft drink. "

There can be a delayed reaction. People should know what they're drinking.

I drink small wines. When people get me large wines I throw half of it away in front of them and they don't do it again.

She thought you didn't want to ask for doubles because she was paying. She was double guessing and got it wrong, just tell her in future if you say singles you really mean singles, you're not being polite.

It isn't the crime of the century but it obviously isn't okay.
I like to keep track of my alcohol intake as I know my limit and don't want to end up very ill the next day as I'm a lightweight. Whatever her motive, she was completely in the wrong.

The friend ASKED OP what she wanted. Then ignored her choice.

As others have pointed out, if OP had been driving first thing next morning, she'd have been over the limit. And that isn't funny.

Oh ffs, the accusation of drink spiking is absolutely wild! In my opinion she was being generous! Who on earth buys singles, by the time they've added the ice and mixer, it barely tastes of alcohol! I don't think I've ever asked for a single so I automatically say "double g & t please", perhaps it was the same for your friend.

Send her to me OP. All my mates do exactly the opposite.

Spiking is very different.
I think I'm responsible for myself. Even if I thought the drinks were singles, when I start to feel drunk I could choose to move to a soft drink. Or stop drinking altogether. I don't do it by the number of drinks I have, alcohol has a different effect each time I drink .

Don’t be so melodramatic 🤣

Some very dramatic replies on here. She was trying to be generous and didn’t want money to be an issue. Just have a quiet word with her next time you’re out to let her know a single means single. No doubt a MN’er will be on soon to tell you to phone the police 🙃.

She spiked your drinks essentially. But why, that's what I would want to know.

For her own entertainment? To mask her own drinking? She definitely wasn't thinking about you when she did it.

Previous heavy drinking me would have been happy! Now sober me thinks this is basically poisoning you without consent!

What?! A unit of alcohol is the same whatever you add to it! The drink tasting weaker doesn't mean that the alcohol has vanished! A double rum is still a double rum!

Why did she even ask if she was buying doubles anyway.

YANBU
If a bloke did this to someone on a date it wouldn't be ok then, would it?
I don't have huge tolerance for alcohol and like to pace myself if drinking.
I don't want to feel rough the next day, vomit in the night or be over the limit for driving the next day.
I don't think there was malice in it but she needs to understand why what she did wasn't on and to make sure it doesn't happen again.

My friends and I would be the same. No malice intended and just trying to be generous!

Its a form of spiking and completely unacceptable.
Id be having a serious conversation about boundaries with your friend and reconsidering if its worth having someone like that in your life.

When I asked her she said she thought I was asking for singles because I felt bad about the cost so got me 'sneaky doubles'

I don't agree with her ordering doubles when you asked for singles but I don't think there was malicious intent there. Maybe she genuinely thought it had something to do with cost and thought she was being generous to you.
She obviously didn't think of the consequences or any possible reasons beyond the cost.
I would just have a chat with her and tell her you know she was just being generous but please don't do it again because you prefer singles for x,y and z reasons and that she also shouldn't do this to other people either because they also might have x,y and z reasons for not wanting to drink so much alcohol.
If she were to do it again after being told that then you know there was something else behind it rather than just thoughtlessness.

It’s definitely not ok! Reminds of the time I was 18 and we were all drinking with the landlord on a summer’s evening. He kept filling my glass with wine so I had no way of knowing how much I was drinking. I ended up beyond wasted, vomiting in flowerbeds. My mum collected me and I fell out of the car to throw up on the pavement. It was an awful experience 😭

Someone buying me a double, if I asked for "rum and coke" wouldn't bother me, in the slightest. Tbh, I'd probably half expect them to. The difference in price between a single and a double is pretty negligible in a lot of places, and I know when I've had enough drink, whether that be after one or after ten drinks.
BUT it seems odd to ask everytime if you would prefer a single or a double, and then ignore what you ask for. If she was going to ask, I would EXPECT a conversation to be had along the lines of "single/ double?" "Single" "are you sure? It makes more sense to have a double and make it last longer, it's cheaper".
Having said that, I'm struggling to believe that you didn't notice you were drinking doubles, rather than singles.

So basically some people think it's ok for friends,family or a partner, someone you are dating or a total stranger to pop an extra shot in your drink? Is that what some people are saying who think the op is being unreasonable? Because, if you don't know about it and it isn't consentual, that is what it is.
