Being a delivery driver is also a way more dangerous job. Sounds like your place's work balance was fucked though, where I was drivers had to do dishes, prep ingredients, work the oven, and help take phone orders, plus do most opening and closing tasks since insiders were basically only around for rush. Basically the only thing you were exempt from was working the make line. I've done both and still think being a driver was better overall, though. It's a lot easier to sneak away for a break when I was getting stressed and the pay was definitely better even with the cost of car maintenance.
