Here are my 2 worst.
1. I went on a date with a large man I didn't know too well. We met at a Chinese restaurant. I thought it was weird he didn't come pick me up. He showed up on the mid-summer date dressed in layers of sweaters. He thought it hid his size, but it just made him visibly sweat horribly. Try eating dinner across from somebody dripping sweat on his plate. First half of the date, he just ate and ate and ate. He said "I used to be over 500 pounds, switched to diet soda and lost almost 100, and have been healthy and fit since." 400+ pounds is not "fit". He got out of breath, I mean just eating dinner was exertion. I don't care
