The worst thing I have sold in my whole life was...
..frozen meat from the back of a van
I was waiting for my visa and was not able to work. No money left so I had to find something to do. Down in San Jose, CA there was this guy that had 5-6 vans with a big freezer in the back. It was just to drive around in the suburbs and sell meat to people.
Fucking worst thing I have ever done
