person A: Man I feel so dirty and bad
person B: What did you do?!
person A: I went to the bar the other day and my waitress was so awesome!   I was so drunk at the end of the night and forgot to give her a tip :(
person B: Lousy man! What can you do though...if you're a regular she'll understand when you bring her extra another time.
person A: Yeah I go in there a lot.  Next time I see her I think I'll slip her a 20 or something
