From u/mentalfoam Tales From Retail:

Many moons ago I worked nights in a petrol station fairly rubbish job but paid the bills. Now this station wasn't in the nicest of areas so had frequent shoplifters. My attitude to it was as long as they weren't blatant I didn't care in not gonna get stabbed over a pot noodle.

One time tho there was a regular thief was in just him. Clocked him stick 2 bottles of milk under his jacket thought I'd mess with him.

So using the remote key I turned off the sensor for the door. Told him that we had a new thing added to the door that detects if the person has unpaid for goods and automatically locks door.

He said didn't have anything and to let him go. Explained that it's new and that only cops can open it sorry they should be here any minute.

I said look mate I'm not saying that you have anything on you but if there is a chance he has anything to put it back and it should open. Que him sheepishly put the milk on the counter as he done this I turned the door back on. So he went to leave and it worked. Still makes me giggle that the local thieves thought we had a magic door lol
