If it's the same price/they had no problem paying for the more expensive item (if there was one, the OP said there was no difference) in the interest of customer service they should've just let him have it. I can understand a cashier not wanting to go out on the limb for this w/o management approval, but they should have forwarded the decision to the store manger and if he refused..well...I just know that if this was my business and the prices were the same, i would've given it to them.
