I hate it when receptionists tell me, "You're early" for arriving 10 minutes earlier

It's one of my pet peeves. I hate it. I arrive 10 to 15 minutes early because there might be paperwork to fill out, or simply because traffic is horrible, so I'd rather arrive a bit earlier than late. Every single time it happens, these receptionists loudly say, "You arrived early. Your appointment is at [insert appointment time]." I respond annoyed, "Do you want me to wait in the car? I drove from far away." I could understand if I had arrived 1 hour earlier, but isn't arriving 10 minutes early desirable?
