Scenario: Guy (just an acquaintance) walks into the doorway of your office standing there looking at you expecting to either ask a question or start a conversation (you have no idea which). However, you're on the phone in the middle of a conversation with a close personal friend. Do you:

A) tell your phone-friend to "please hold" and see what the doorway-friend has to say. Once you acknowledge him he starts into a conversation that could take several minutes regardless of the fact that you are already engaged in conversation with another person.

B) snub your doorway-friend by continuing your conversation with your phone-friend and merely giving the guy in the doorway the obligatory head nod of recognition indicating your intent to not disrupt the phone conversation.

It's really a gamble. In scenario A, you don't know what you're getting into by allowing the other guy to interrupt you. You risk being rude to the guy on the phone. In scenario B, you risk being rude to the guy in the doorway but you have know idea what his intentions are.

In the words of Keanu Reeves in Speed, "What do you do?"
