When I tell you I have never experienced a bartender (male) stealing money from me because he thought I was too drunk to notice. The thing is I'm a big tipper in general but for a person steal money from me without giving me the option to tip you is a huge disappointment in my eyes. I even brought it to his attention and he was like "what do you want me do about it?".
All I will say is pay the exact amount because he doesn't believe in giving you the exact change back.
Sincerely,
