Our school office staff are, without exception, all lovely. I must be lucky.
But YANBU about your child being late, you're right and we do all oversleep sometimes for whatever reason. I clearly remember my Mum doing the walk of shame to school with us when she's slept in after a heavy night on the Gin (joke BTW).
PE kits washed half-termly here too. Not too stinky, could be worse.
