In 1972, the dealership I worked for was about to move into a new building. Each Tuesday night, the service department and parts dept. guys would meet out there for a clean-up party.
Owner supplied beer and Col. Sanders, and we washed down steel beams, walls, cleaned up behind contractors, and moved in, and painted, some equipment, etc.
One week, the car wash guy wanted in on the free beer and food, but he wasn't much help other than eating and drinking. When we ran out of beer, we told him it was his turn to buy.
He hesitated, but did go to the Liquor Sore.
He came back with a 6-pack of Black Label, and a jug of cheap wine.
Service Mgr. said we were about to leave anyway, so we didn't drink his beer, or wine.
Next week, he showed up with the same 6-pack, and when he opened one, you could smell it for a mile. Nice guy, but quite all there!
