It's not my fault I don't want to pay 13 dollars+tip for a cocktail when I can make 20 of them at home for the same price.
Oh, certainly not your fault, but you might be better staying at home. Why agree to go out somewhere with your friends if you are just going to drink water?
What do you think I'm an amateur? Club soda with lime, in a highball glass.
We all have choices.
Then stay the hell home, please. Everybody will be happier.
When I organize something like this either A) I think the cocktails/beer/food/etc. is genuinely amazing and if you don't then you should stay home or B) I'm more interested in the company and I think the ambiance is acceptable.
Even with similar incomes, as young adults in our mid-20's, working hard for our money, we'd like more control over what we end up paying for.
