I can speak of Chile with some authority, having lived there for 4 years. When it comes to customer service, it's overall very poor, especially compared to the states. Two things in particular cause this, 1. the citizenry does not demand it therefore they don't receive it. 2. You cannot fire employees without great pain. With these two factors, (there are others as well), customer service in restaurants and in retail is, let's just say poor.
