Almost got denied on the guides at BB last night. I had 4 (1 of each title), the part-time girl rang them up with a full-timer looking over her shoulder. As soon as the first one rang up at a penny, the full-timer said "We can't sell you this for this price." I told her that I was just in the store the day before and bought a couple. She went over to her manager, and came back a couple minutes later to tell me "My manager said that I can't sell these to you." So I walk over to the other register where the manager is checking people out, and asked her "Is there some problem with my transaction?" She says "Yes, we can't sell those for a penny." I explain to her that I was just here yesterday and purchased 2 guides for that price. She looks over her should at another manager, asks him in a hushed tone if she can sell them, and then the guy looks over at me and says "We aren't supposed to sell these." I repeat that I had just purchased some the day before, and he then replied "Okay. We can sell you one guide."
I told the guy I want to buy 4 guides, and he says "Okay, we can sell them to you as long as they are different titles." I told him they were, walk back to the original register where my guides were waiting, and tell the cashier that they said it would be fine. The full-timer then yells over to her manager (who is like 30 feet away) "Is it okay to sell these?" After a quick confirmation from the manager, she sells me the guides.
Geez, now I know which cashier to avoid in the future. At least I got some guides for trading, though.
