"Worst parking attendent"

I'm wiring the review in regards to a specific incident that took place less than 30 minutes ago m, I'm a delivery driver went to deliver food for the NHS staff, as I do regularly, i parked up on an ambulance bay as I was only going to be 2 minutes as the staff will come and collect the food.. I was told to move my car from the bay which I did then the car park Attendent started hurling abusive language towards me and swearing , this was witnessed by the staff who apologied to me they also explained I was here only for a few minutes to drop off food but they continue to abuse me and the staff , when I asked for their name they started to get aggressive smashing their fists against their chest and swearing at me. They also radio to call security saying I was been aggressive, further more they were swearing at me again.!
