7) You think everything's better in America
Your default is to compare everything you see, eat, hear or experience in any way to something stateside. “Wow, these Pyramids really sure look like the one in Vegas”.

Waitress delivers what can only be an amuse-bouche. “Ma’am, I ordered an entrée”. “This is an entrée -- don't you realize 'entrée' literally translates to 'appetizer' everywhere apart from North America?” "Umm, yes, I just meant I wanted THREE entrées".
9) You think free water is a god-given right

10) You want ice in everything
"Waitress, sorry to bother you again, but there's no ice in my (sparkling) water". What sort of heathens drink water -- and SOFT DRINKS no less -- without ice?
