i'm sure it was about the other people in the restaurant, stop trolling
Trolling? It's called presenting my opinion and viewpoint on the issue, not "trolling."
I might have a bit more sympathy for her being fired if I bought her "we were too busy" excuse for not being able to follow the policy as well as I'd hope.
If you can find me evidence that there was enough people in the restaurant for the shift manager to be "busy with customers" "in the back" while the two counter people appeared to restock, I'd love to see it. I'd also then presume the robber was on drugs in that case, holding up a packed restaurant and all, unlikely, but I'll admit it does happen. I'm not unreasonable.
Still doesn't change the fact that she has reportedly repeatedly violated company policy, which was I'm sure put in place specifically to mitigate robberies like the one that happened, but in that case, if she was reasonably too busy to have done it yet, then I might just give her a warning and tell her flat out if it happened again [her not moving the cash to the vault] she'd be fired immediately.
