It literally is because they go too fast. I worked there for a while and we have a 80 second window from when you pull up to get your order, have you pay, and get the order out. Which is fine when you have everything made, but we can't make things until they're ordered. Once we go over that time out managers rip us a new asshole. Worst place to work in the world lol

They probably just stack them too fast. When I order the filet o fish the cheese is always on one side more than the other
