When I picked up my car at the dealer, the salesman parked the car facing the show room, and the only thing he showed me was how to get the seat into the lowest position and as far back from the steering wheel possible (I'm 6'2").
When I got into the car to leave, I noticed three salesmen standing in the showroom directly in front of me with their arms folded across their chests, (and a smug look on their faces) just waiting to see how long it was going to take me to figure out how to get it into reverse.
I guess I disappointed them, because it only took me about 15 or 20 seconds to figure out. But I have to admit, (at the time) it seemed like it took much longer with them staring at me.
