First aid service and medical staff nothing to say...

First aid service and medical staff nothing to say. Service staff in dark blue shirts 11:20 am: I wait for a wheelchair for my 78-year-old father, two operators pass by and when I ask "the wheelchair for the gentleman please", one sits on the wheelchair saying "which gentleman haha!" while the other pushes him away laughing. I reach them and this (tall and sturdy, very tanned and with earrings), approaching two fingers from my nose, with a threatening air asks me "what problems are you having? Looking for trouble ??". From complaint, I hope that within the corridors of the P.S. there are cameras. The same operator, in the early morning, had heavily reproached my father (I repeat, 78 years old, disabled) because, on the stretcher in the corridor, the sheet was being adjusted to cover his legs. The Health Department should intervene.
