Yeah, that's okay. It isn't rude in any way to pace outside my door and then stand inside my door with your arms crossed, then come in and dive into my bag of jelly beans making a lot of noise rattling the bag while I am on the phone. I GET THE HINT LOUD AND CLEAR…you need me for something. The fact that I am on the phone really doesn't matter at all. It's not like it could have been important or anything…though our definitions of important could also vary along with our tolerances of rudeness!!!!
So, I get off the phone...it's a ten second conversation that could have waited!!! Grrr...must be nice to be the boss!
