Have you ever been beaten into a space you were actually driving into at the time?
This has happened twice to me, at the same supermarket car park.
The first time I was incredulous - I said to the old dear "What did you think I was trying to do?" I had just lined up to reverse into the space and she drove in forwards as my car was actually moving.
She just shrugged her shoulders and trotted off.
The second time it happened, it was right at the end of a dead-end aisle. I was reversing into the space and the other driver had moved forward into it from the space behind, again, as I was obviously reversing into it.
As luck would have it, the space opposite the space they had nicked, was occupied, but they could get out forwards, so I waited till they had gone in to the shop, then I parked in front of the space-nicker. And made sure that I got every last item on the list. And spent time browsing things I had no intention of buying.
When I got back, an hour and a half later, the driver was livid.
What a shame.
