IP, I was bribed at the supermarket this evening.
I bought some store-brand laundry detergent that was on sale. By your definition, this was clearly a bribe. If the supermarket hadn't offered me the "incentive", I might have bought one of the name brand competitors. So they must be offering me this money to stop using the competitor's products. Do you feel that's ok? Is it normal business practice? If it is fine for you, then I suppose it will be fine for me, too.
