I worked at a fast food place where our power went out. They forced us to keep ... open and selling anyway. The 240v was out so no grill, but 120 outlets worked so we could make coffee/tea. That was about it. Cash registers didn't work. I was writing everything by hand, calculating tax, etc, keeping records. 2 hrs later, the regional manager - WHO HAD TOLD US IN NO UNCERTAIN TERMS THAT WE HAD TO REMAIN OPEN DESPITE NOT HAVING POWER - came in and chastised me for 1) not wearing the full uniform (we had no AC and it was July, so I took off the tie) and 2) handling money without a register. "You can't guarantee your numbers are right - that's what computers are for". "But... they're down, and you said to stay open and keep selling". "That doesn't change the fact that you might be making mistakes!" Insanity.
