I'll have the yellow

So today at lunch two friends and I went to Bar Louie.
We were exited that 1. no one was there and we could sit where we wanted and
2. we never had lunch there before so it was a new experience.

So when my friend M went to order the waitress asked "what kind of cheese do you want?"
M said "do you have American"
the waitress then replied "umm...we don't have America, we have yellow."
M says "umm...ok"

Ah, is she really that stupid or do they make them say that?
So we thought of other options:
white
white with holes
white with specks
white and yellow

We decided we now need to go back and try this again. We want to see what the other waitresses say. It was quite hilarious.
