In reply to Mick Ryan - UKC and UKH:
That's truly awful and downright shocking. I had to watch it a couple of times to confirm that what I was seeing was actually happening.
The man is obviously a complete and utter unthinking idiot and his actions beggar belief. The film crew should have intervened much, much earlier and insisted that he wear the appropiate PPE safety eye wear.
Absolutely appalling behaviour, he could have had his eye out!
