Imagine this scenario: I'm at a store, looking around, then realized I left my wallet in the car. So I start to exit the store, when suddenly an employee stops me. He may even have a special sales flyer -- but I can't get past him unless I tap him on the shoulder so that he steps aside. At this point, instead of going to get my wallet, I will get in the car and find another store. It is the same type of irritation that I feel when, after making a purchase, a store employee stops me at the door to check my receipt and compare with the contents of the bag. I've already stood in line for 20 minutes, forked over money, and now they are holding me up for another minute? No thanks.
