It takes a major type of person to do it! This is way harder on the nerves than I thought it would be. My nerves are fried anyway, this has been overload!
AYFKM? I did convenience store work in college. Yeah, it was boring. The worst part were the drive-offs--this was in the days before pay-at-the-pump and the owner had a policy of never making customers pre-pay, with the expected results. All I could do was take down the plate if I could get it, file a police report, and hope the boss didn't get too pissed off--and he didn't because what could he do? It was HIS policy, despite my suggestion to "lock down" the pumps after dark.
Do a little mopping/cleaning, toss the nacho cheese once a week (I'll never eat that shit) and run a register. Blast the radio when nobody is there, which is most of the time. About the only real fear I had was someone robbing the place, but never happened.
