I go out with one of my friend. This friend is so cheap that he doesn't to pay for anything. He even once embarrassed me in a bar.
That sounds frustrating, especially if they are inconsiderate and drain you of your funds. They sound kind of entitled.
He asked the barman if he can bring his drinks from home. I was so embarrassed.
Oh wow, that must be embarrassing to deal with. Sounds like they are going through a financial situation, but they should at least talk to you about it since you two are friends.
