Went in a car to pick up a part, there was no parking spaces open. I parked behind the service truck leaving plenty of room for it to get out. I was yelled at by the service department that I couldnt park there as they had to be able to get their truck in and out and to park in the fire lane instead which totally blocked the entrance as there was already a delivery truck there. This all took place after I was halfway to the door having to use a cane for assistance.
