That's too much of a a hassle

I was working in electronics when some guy walks up to me and wants a price adjustment of an item he had purchased about three weeks ago. I explain that he can only get the price adjustment within 14 days of purchase. The only other option is to return the item and purchase another one at the sale price. He tells me that's too much of a hassle. I tell him he can go to the service desk, get the manager and see if they will do anything. Before he does that he asks me "What if I bought another one right now and returned the old one later?" Wait. Less than 20 seconds before he told me that was too much of a hassle.
