Non-Americans who have been to the US.. What is the weirdest thing about America that Americans don't realize is weird?

The exact opposite experience if you're non white. I'm light skinned and get normal service. I go out with certain friends and suddenly we're getting ignored and waiting longer than people that came in way after us. We just end up ordering pickup or avoiding certain places all together.

they do it hoping you get larger tips for being attentive, because it's not enough that you're paying the restaurant; you need to subsidize the wages of their workers.
