Haha, you will!! Service is Chile is terrible. They don't care. It's really odd. Even Chilean restaurant owners would prefer to hire immigrants, like Colombians - no joke! Chile has a lot going for it, but if you want good service then keep looking. :) Colombians are known for taking really good care of you though. I don't know about the other Latin American countries. My guess is Chile's at the bottom and Colombia is at the top.
Enjoy your trip. That's awesome.
