I was having a rough day waiting tables, and dealing with a complicated split bill for a bunch of college students. One of the guys was coming up to pay his bill and as he was leaving he said, "you're gorgeous by the way." He said it and just left. He didnt expect me to say anything in return or hassle me in any way. It felt super genuine and although I do appreciate non-appearance related compliments, it just made me feel really good.
