I finally quit and decided to drive by for some French fries. When the worker at the window recognized me she said, “It's just me and the manager for the after-school rush. You can come in and work if you want.” I was fricking gobsmacked. One of the reasons I quit is because they kept understaffing the second biggest rush of the day, and as a wage slave, you were supposed to buckle down and not question why that shift was chronically understaffed.
EDIT: I went by after the lunch rush when they were slower to see an old friend.
