It's almost like when we burn a derelict house down over here, one room at a time and get the new kids in there and teach them about flash-over and fire science/behaviour, it's in a training environment, so they aren't put at any real risk of injury.
I can recall being a
'noob BBQ' crew participant , blinded by smoke etc , with a training officer screaming
"are you !%$#@ jokers all i get for my tax dollars?"He definitely left an impression....
