The two guys in the video ordered every single item on the McDonald's menu, simply because they could.
However, in spite of the fact that the customer is always right (yeah, right!), and despite the fact that these two guys were perfectly willing to spend hundreds of dollars in a single transaction, the employees initially refused to comply with their order.
"I want the whole entire menu," the more vocal of the pair continued to insist to the staff. He then clarified that he wanted "everything from the McCafe to the Dollar Menu."
Their very no-nonsense server clearly did not take them seriously, abruptly responding, "there's no ice cream" as the machine was broken "so you can't get everything." Afterwards, another employee asks the man, "[do] you have the money to pay for that?"
And, well, it turns out they did. The men shelled out a whopping $250 for a feast of burgers, salads, wraps, ice creams, shakes, hot coffees, iced coffees and well, everything else.
It's pretty unbelievable that anyone would want to buy everything off a menu, knowing full well that they'd never be able to finish it. But if that's someone's idea of a good laugh, then to each their own.
