My favorite subreddit currently is Choosing Beggars. Its essentially people capturing conversations with insane cheapskates trying to get things for free or at absurd discounts. If I could have captured any of the conversations Ive had with this guy I went to school with, he would be in the hall of fame. He would to secretly fill his Grey Goose bottles with Popov and then charge anyone who took a shot. Another time, he offered to drive a group to a party store to pick up Halloween costumes for a party we were all attending that evening, and then demanded everyone throw him $10 each for gas. The store was 15 minutes away. He would invite you to lunch, then demand you compensate him if he swiped you into the dining hall. No tact, no self-awareness. Focus: Who is the cheapest person you know?
