Theres a man who walks around the mcdonalds by my house, wears raggy clothing, and has turrets. Kids on the bus in junior high would call him radio.
I saw the guy sitting outside mcdonalds at 4:30am in 30 degree weather. I ordered my food, drove around again, and gave him $20.
I found out later from the manager who I know that the guy is far from homeless, and lives in a house about a block away.
