Once, but he was naff, and that was even when he bothered to turn up on time.
On his last day at work - on the way to our first job - he started crying. I was like "What's wrong with you?" He said "I'm sad because my grandad died!" Now I'm not heartless and I had been giving him a tough time about his time-keeping, so I said, "Oh why didn't you say? Look, I'll take you home now. When did your grandad die?"
And he said "Last year; it's the anniversary!"
I thought to myself, you're not coming back to work with me you flipping wet blanket.
