I found out the hard way that a job I had once (DIY store) had a hidden panic button under the counter. I was just fidgeting while we were closing up, hands found it and did their exploration thing.

I mean it happens, the security company sent out a van already (as they should) and called to confirm. They charge a fee (just over €100 I believe? Or €250? I forgot) for false alarms, but that's fair enough. Better safe than sorry.

Anyway, a DIY store with at most 100K in the safe (weekly takings at the time, most of that was probably electronic) is probably a lot less serious than whatever you were working for, to have it surrounded by law enforcement.
