It certainly seemed unconventional. But then it’s been about 18yrs since I last did one so perhaps graphic roleplay is the done thing now.
My favourite line of the course was when one guy had prompt sheet thingies on his forehead and people had to describe symptoms to him without using the exact wording.
For ‘swollen red tongue’ he’d guessed all but the last word. So one bloke said to him “it rhymes with mong!”
I think the tutor had well and truly lost control by then. He did say he thought he was in trouble when it wad the first course in a long time that was all men. All coming from construction or manufacturing.
