I am really good at ordering drive thru at McDonalds. I can order twice as fast as most people.
For instance when I am ordering a Big Extra combo I order it like this
"One Big Extra Combo, no cheese, diet coke, not super sized"
By telling them no cheese what type of drink I want and preempting the super sized question I save exactly 8 seconds off my ordering time.
Amazing I know. Some of us are just naturally blessed at some things.
