When you go out with a member of the opposite sex who pays for you, do you check the tip if you have a chance to do so surreptitiously? Does it affect your opinion of them? Would you call someone out on a really bad tip?
I went out for drinks with a boy the other night and he paid the check while I was in the bathroom, which I thought was sweet (and I hope it didn't look like I timed it cause I just really had to pee), and then he went to the men's room before we left and I looked in the checkbook. It was like, 40%! I don't know if he expected me to look and wanted to impress me or what, but it certainly worked!
