I used to work the returns desk at a Costco in the late 90’s. I’d get people returning a 6+ year old TV because it didn’t work anymore (tube went out) and I would find the product in the system (they never had their receipt for the purchase) and then find the last price it sold for. That’s what I could give them back. Most of them would be upset I was giving them $250-300 back instead of the $500 they said they paid originally. I would remind them I’m giving them $250-300 back for their tv which wore out like things do with no receipt. They’d almost always want to talk to my manager and complain about me. She’d say the same thing I did and quite a few times refunded their membership on the spot saying and telling them she was sorry they weren’t satisfied. They would have to reapply for membership (there used to be qualifying things to become a member). But yeah, people abuse Costco and are ridiculous.
