I've worked in a pizza place and known other people who have worked for pizza places, and none of us described it like a prison or felt the need to piss in a bottle.
No, instead they have a dangerous business model where they force their drivers to get to a location in 30 minutes or less causing them to weave in and out of traffic and crash in hopes of getting a tip. Much better than bottle pissing.
The what? That 30 minutes or less thing was outlawed in the 1980s, specifically for the reasons you cite.
Yeah, but they do get free pizza.
Amazon, meanwhile, won't let anybody get free snacks from the bins except for mice.
I mean, if you want to play that game, capitalism itself exists on the back of a pool of exploited low-wage workers.
