So my colleagues get together once or twice per week and go grab lunch/dinner together, each time someone else pays. The price is roughly the same each time and there are 7 of us. Last time it was my turn to pay. so far so good. Then while we were having dinner, 2 of the people ordered a bottle of wine. Which only they drank. 3 of the people are non-drinkers. In no other occasion when we have eaten together did anyone order alcohol. Those two then ordered a second bottle , which they proceeded to drink. When the bill comes the wine is 2/3 of the bill. Now I am really miffed. most of our meals are shared platters. so every get something. these two got something that only they enjoyed. I then told the waiter that I would like the bill separated , into food and alcohol . And told then since they wanted the wine and no one else had any they can pay for it. If it had been beer pints or something reasonable I would have just paid, but these were $80 bottles of wine. They never at any point asked if it was ok for them to get them. Now they are pissed off at me. Calling me cheapskate. Fortunately the other people who were there think I was right and would have done the same thing. However other people think the two are right... Now I am asking what you think/would have done.
