If you have ever been to a Rat Shack Electronics Store, you know that the whole store is pretty much open.
Had a guy walk in one day when it was moderately busy. He walked right up to a display of $300 RC trucks, picks one up, and walks right to my register and demands that we give him a refund.
Thankfully when I told my manager what had happened, he kicked the guy out and threatened to call the cops.
That was one of the few stores I had ever worked for that the manager didn't take crap and was on the side of the employees.
