Tim - your time as an unqualified, unvetted child minder at Lingfield reminds me of my own unprofessional effort at the same place. I was a bus driver. Just a mini-bus, but really, it would have been much better if I'd been looking after the kids.
I picked up a load of Indians from Heathrow. They had tons of luggage, huge cases I'd never seen the likes of before. But the mini bus had a roof rack, with deep bars all around. So I jammed all the luggage in there. A guy asked if I wasn't going to tie it down. I said it would be fine, being so heavy and jammed in. Also I didn't have a rope or a net or know how to tie knots.
The Indians were pretty fed up - they'd had a lot of delays, and the Lingfield event was ending soon. They were tired, and just wanted to get there.
So I hit 70mph in the outside lane, and checked my mirror and saw a very confusing kaleidoscope of colours. Sari's blowing all over the place and behind them, case and trunks bouncing on the road and breaking apart. Traffic in all three lanes stopped. I reversed back and we all all gathered everything up off the road, and just jammed it into the bus like so much rubbish - much of it now was. Some were in tears.
Of course, the man was right, I should have tied it all down. But what did I know? So now they were tired, and of course very upset. It did flicker through my mind that they shouldn't be so attached to things! But only for a moment. That wasn't at all appropriate. There was no getting away from it - feel their pain, and feel terribly sorry.
