When my husband and I arrived at a car dealership to pick up our car after a service, we were told the keys had been locked in it.

We went to the service department and found a mechanic working feverishly to unlock the driver’s side door.

As I watched from the passenger side, I instinctively tried the door handle and discovered that it was unlocked.

‘Hey,’ I announced to the technician, ‘its open!’

His reply, ‘I know. I already did that side.’
