We had an idiot try to swap out a jug of milk last night, because it expired after he bought it. Two days later. Obviously I left a note for the manager to let us put things on sale as they approach their expiry date, but we can't do that. He had demanded a second opinion because the cashier told him no and was just pissed when I said the same thing
He then grabbed another jug of milk that was also two days from expiring. Because apparently he just chooses not to check what he's buying.
Another woman was demanding a refund on a battery which wasn't working. It's a motorcycle battery, one that comes empty but with a box of battery acid included in the package. Always. But they for whatever reason decided not to put the acid in there, ruining the battery. The manufacturer offers free replacement but she wouldnt accept anything less than a full refund. I even called and replacement is the only service offered by the battery manufacturer, and we don't offer any warranty. Especially not a dumbass warranty. But she was angry and rude the moment she opened her mouth and just got angrier and angrier as I explained the situation to her, claimed we sold her he battery without a box or explanation of the warranty, which we would never do, and accused us of accusing her of lying (which is true, it was obvious she was), demanding to speak to the manager (who was standing right there and was the one who pointed out it had no acid) and then demanded to speak to the owner, so we pointed her towards the tribal council offices. But she just kept getting angrier. So the boss threatened to call the police, at which point she fled, threatening to send her husband in after us. It was horrible and hilariously stupid.
