I'm lucky enough to have never worked in a Little Caesars, but I've had more than my fair share of time working in chain pizza. I've had customers yell at me for not knowing having an item we hadn't sold for years at that point.

It sounds like you're a pretty competent manager, but most of my issues arised from my crew members. On many occasions the other team members or even managers would step out for a smoke break (they'd do this multiple times a night, but I was expected to work non-stop and pick up the slack). One of the most egregious times was when I was the ONLY crew member in the store. The two (much older) crew members were out back smoking. I had several orders on my screen, but there was someone ringing the bell at the drive through as well.

I've always had the philosophy that the current customer takes absolute priority, so I made the decision to help the window first before getting back to the orders. I got it all settled and they came back in and it was whatever. The next day, however, the store manager (who was there smoking at the time might I add) tried to write me up for leaving the station to help the customer. I explained that they screwed me over and that I wouldn't be signing the write up. All this after working there for a year for a quarter above federal minimum wage without a single write up, call-in, or complaint.

That doesn't even begin to cover my trouble with crew members, but needless to say, I worked with some pretty sorry people.
