When is is ok to use "oye"?

Question

And I'm asking how it is used in different cultures.

Answer 1

I've heard it use by Puerto Ricans, Colombians, and Guatemalans as "Hey, look here..." or "Hey, listen up..."

You can call your friend, who's across the street, to get his attention. "¡Oye, Pedro!"

¡Mira! is used in the same way.

Answer 2

It´s also used in Spanish restaurants to attract the waiter´s attention.

In a restaurant, we use, "Oiga," not "Oye." "Oiga" is conjugated for "Usted." - 005faa61, Jun 7, 2010

In that case the middle aged Spaniard I was with was incorrect? He certainly was´nt using subjunctive - caza, Jun 8, 2010
