Are you an obnoxious business traveler?

If you follow any of these 10 worst-practices, you may just be an obnoxious business traveler. Having traveled with a DYKWIA (do you know who I am) recently, I'd put that one at the top of my own personal list. Blech. I love this response, from the comments:

The "do you know who I am" line reminds me of a story: a self-important person pulled this line out on a flight attendant, and she immediately went to the PA system and said: "We have a passenger here who doesn't know who he is. Can anyone help him remember?"

Thanks to Bill Geist for the pointer!
