What are the top 10 things Americans don't know about the rest of the world?

the American who spends several months each year outside of the USA , on him
to learn a thing or two:

Refills are not automatic. You pay for them. Everywhere.
Ketchup is not always free, even at McDonalds.
There is nothing special about a U.S. Dollar -- and nobody feels flattered to get it as a tip.
Nobody else likes the idea of tipping 20% or having sales tax added as an extra. Nobody.
Nobody else ever asks where you go to church or whether you go to church.
Football is the world's most popular sport and it is not played by steroid-bloated giants wearing huge helmets.
Nobody in the world wishes they too had a Second Amendment to allow everyone to conceal and carry a weapon.
Not everybody in the world lives with the fear that a medical problem will send them into poverty.
That people from other countries actually take long family vacations without the fear that they will lose their jobs for taking them.
That not everybody in the world speaks English.
