This is actually not the first time this kind of thing has happened...

So I went to buy a juice at the store and the cashier was an Indian guy. He was giving me my change and suddenly he said something like:

Cashier: lustris arkabagad
Me: Um...are you talking to me?
Cashier: Are you Indian?
Me: uh, no, I'm Mexican.
Cashier: Oh
Me: Are you Indian?
Cashier: Yeah...Well, actually I'm Mexican too. (Laughing sarcastically)
Me: No man, I'm serious, I'm Mexican. People have told me before that I look Indian, I wish though (that I could understand him), but I'm Mexican.
Cashier: (Still laughing as I headed out the door)
