"Drop of area full of parked cars"

My father had an appointment at Crosshouse. We parked in the disabled bays. I ran out to grab a wheelchair for him, but trying to get to the entrance was a nightmare. Eventually we managed to get to the appointment but coming out some thoughtful person had parked their car over the pavement in the pick up and drop off area. We could not get the chair through at all. I had to go and collect the car while my father struggled to the road. I am appalled at this.

The next day we had another appointment at the same clinic. Once again the pick up and drop off area was covered in cars all parked with noone about. My question is why is this allowed to go on? Why do you not have security guards to move people on? I am visiting from overseas and am just disgusted at this and will be forever worried about my father and his future visits to this hospital.
