"Was attending the a&e with a emergency and got a..."

I drove a work colleague to the A&E department wo had dislocated his shoulder and had hit his head rather hard by falling off a pair of steps, on arrival to directly outside the department I parked outside the front doors and got out my van and walked 3 steps to two paramedics who were in there car next to me to ask for help, after seeing my colleague they had to put a neck brace, back brace and try to not move him at all, all of this was taking place in my van!!! They eventually got him out and put him on a stretcher and wheeled him straight in to resuss! At that point I asked the paramedic where I should park and was told so I went and parked. 1week later I get a £100 fine for parking outside the A&E discussed to say the least
