A customer is on the phone in the middle of the bar, not too crowded but a long bar. Guy couldn't have been more than 25. I go to help someone at the end of the bar and on my way back I overhear:
"No, I don't care! She's my sister, she is THIRTEEN and there is no reason she should be doing illegal substances! At all!"
Gave him a few drinks on the house that night.
