The showers in my school were actually so low to the ground you couldn't use them unless you knelt down, bent over or thrust forward. We did occasionally wash our legs off still fully clothed after a big game of rugby but that was as far as it went.
We had 3 teachers in my school, the same the whole way through. Two younger men, one who was shagging a few female NQT year women and another that did the creepy chat you up once your 18 thing.
Generally they were ok. The elder leader teacher taught me for the 5 mandatory years and he gave me a couple of fair bollockings. Once playing football I got the best of him. We were playing footie which sorry everyone I absolutely detest. He saw my lack of enthusiasm and had a quiet word. He said I could be a team player or I could do written work for the rest of the term. He didn't expect me to ask in reply how much, could I choose the topic and where would I be doing it. I was quietly dismissed.
In fairness to him when I did have a fight he let it slide during a time when the school had immediate suspension rules. He also used me as a case study in A Level sports science about motivating people who would do sports but not enough to stop being a fat bastard.
In Primary school, the PE directing teacher was a bit of a cow. Once asking me to do a push up Infront of the class. She was about 20 stone and probably couldn't manage it. I've yet to forgive 8. Year old Simon for not retorting.
