When I worked at a restaurant, this woman that the cashier referred to as Jaba the Hut came waddling in, complaining we didn't deliver her food. We kept trying to explain to her that it was those delivery apps that was at fault, not us. She refused to understand. We got yelled at, she didn't get her food, she'll do this again to some other hapless restaurant, and the rascal got a free meal out of it.
