I can't think of any other industry where things are sold new as damaged goods, at full price, with the promise of being fixed later. And the customers thank them for it.
"Sorry sir, your £26,000 car doesn't have working brakes yet, come back in a month and we'll fix it right up for ya" / "Why thank you!"
"Sorry madam, the chips are still frozen. Just eat the fish now and we'll bring your chips right before dessert" / "Oh, it's to be expected and your very kind!"
"Now your house doesn't yet have a roof. yes, I know we said it WOULD have a roof, but they are quite hard to build so you'll have to make do with tarpaulin covers until Christmas" / "Oh, this will be FUN!"
etc
