Large vs. Big

So yesterday I noticed that we don't use the word "large" for anything other than food.
"I'd like to order a large pepperoni pizza."
"I'd like a large chocolate shake"

McDonalds Person: "Hi this is McDonalds, what would you like to order?"

Customer: "Yeah, hi, I'd like a large cheese burger with a large serving of french fries and a large coke."

McDonalds Person: "Anything else?"

Customer: "Yes, I'd like a large vanilla ice cream cone."


See? We say "Big". That is a big building. Wow, that's really big! Etc. Etc.
