There were times when I was out of work, sitting on a bar stool and have a local cook track me down because they fired a dishwasher or a prep-cook and needed me to cover the dinner shift (5-12 pm) So I would negotiate it and do the job. So depending on the job, I would do dishes or cook. But dishwashing was brutal because you had to clean the kitchen too, so most nights I didn't get done until after midnight.
Then I would walk down the street to my favorite bar and drink beer and play pool for free! Because they knew I had worked my ass off.
