A video shared to TikTok shows the moment an angry woman began to argue with a Dunkin' Donuts employee over a simple math problem.

The woman argued with the staff because she thought a dozen meant 50, so she needed 50 donuts.

She even goes as far as to spell it out slowly for the employees to understand, shouting "Five-Oh!"

Obviously, it wasn't a winnable argument for either side.
