My son is a member of an out of school group and they organised a trip out to the theatre for them which we paid for. When I picked son up he was desperate for toilet and had to go immediately behind a tree. I asked him why hadn't he been at the venue they spent 3-4 hours at had a toilet. He said the leader did not allow any opportunity for kids to use toilet! They had to sit in seats all the time. Surely a leader would ask the young kids if any needed to use the toilet? Either before performance, at the interval or afterwards? Isn't that just basic care looking after someone's kids?
