Well, I'd certainly never heard of giving the old crap back unless the customer specifically requested it. Seems like a cleaner story to say that the old stuff needed replacing, so we did, and get rid of the evidence.
Although if the shop is limited in the volume/weight of garbage they can throw away, perhaps offering customers the opportunity to haul away their own trash is a way to lighten that load.
