To my understanding, it is common courtesy when making a phone call to a business or someone you've never met, to at least say "Hi. This is (so-and-so). I'm calling from (so-and-so business)," shortly after the person you called has answered the phone. Well, as you may or may not know, I work in a customer service environment (for the time being) where my primary responsibility is to answer phone calls from our customers/clients. Just the other day, I answered the phone with utmost professionalism, only to hear the person on the other line bark right back at me, "Do you speak Spanish?" in a very thick Hispanic accent.

Growl.
I immediately took a disliking for this person.

I certainly don't mind people talking in other languages, or not being that fluent in English here in America. But sheesh! At least have the decency to acknowledge the person on the other end of the phone!
