linuxwrangler writes on slashdot.org:the customer is not always right. Best Buy consultant Larry Selden has identified “demon customers” like those who file for a rebate then return the item. OK, I get that one (hey Best Buy: dump those customer-despised rebates and you won’t have that problem…). Other categories like customers who only buy during sales are more interesting. Best Buy declined comment on how they are dealing with those customers. Some stores have actually “fired” customers. Welcome to the end result of all that customer information data mining.”
