The double drive-thru at fast food restaurants. If there’s only one person taking the order, what’s the point?
And what’s the order of traffic in the miraculous event that there are two people taking orders, and both customers finish their order at the same time? Who proceeds to the window first? And how am I sure that I’m getting my order and not the guy who cut me off to get to the window before me?
Now we need a traffic cop at McDonalds!
Who was the genius that thought of this?
