When a man sat down at Claire Hudson’s table at Mac’s Grub Shak in Spring Hill, Tennessee, Hudson didn’t give his presence much thought. He ordered a couple of beers, a burger, and the special: A Coney Island Hot Dog. After he finished eating, he left as quickly as he came. His bill wasn’t much, so Hudson wasn’t expecting a huge tip. However, when she returned to the table, she found $36, and this note.
