>Oh my God. I realize that the cashiers have been ordered to do this (I assume) but knock it off already!
Why should they? If they don't they will get fired. Business goes up or down that cashier doesn't get paid more or less...they have no incentive to risk their job for a customer. These companies are so obsessed with squeezing a nickle out of 5% of their customers because they can _measure_ that. Its 'impossible' to measure losses like you with any granularity, so it doesn't matter. They 'can't' incentivize it.
