Please don't sit in a car in the driver's seat waiting for someone in the store
in a disabled parking spot.

You can wait somewhere else and pick them up in front of the store or nearer than that parking spot. Someone with a disabled parking permit who intends to actually get out of the car and go in may have to park further away than they should have to because you are sitting in that spot when you could have waited somewhere near enough to see the store entrance and pick up the person you are waiting for. To me, it's the courteous thing to do.
