Some years ago my brother in law called the police as his car had been stolen from a multi storey car park, I was with him

turned out we were on the wrong level.
Again, a few years ago, when I was single, a ladyfriend was staying over, next morning her car had gone. I called the Police, a friend came to collect her and had seen the car parked up in the pub car park.

Turned out her husband was following her, and moved the car to teach her lesson. I rang the Police who were OK. I might add that they were supposed to be seperated, though still living in the same house.
