Remember this guy?

Whenever I see someone having a private talk on their bluetooth enabled cellphone and at the same time trying to strike a conversation with me, I find it to be mildly annoying at first. Not to the degree Robert De Nero exhibits in the movie Taxi Driver (1976). But frustrating to some extent. I don’t know for sure if the guy in my front is talking to me or the person at the other end on his cell. If he looks at me and says something, and I am about to reply, he shakes his head and points to his bluetooth device wrapped to his ear indicating that he is actually talking on his cell. Then when I politely withdraw out of courtesy (not attempting to overhear his conversation), and resume my work, suddenly he addresses me with a pertinent question. When I am about to answer, he motions me to stop, goes back to his buddy on his cell. If this happens a few times before our transaction is over, I find myself in the place of De Nero in the movie.

You can see why:

	You talkin’ to me?
You talkin’ to me?
	You talkin’ to me?
Well, I am the only one here !
	Then, who the hell are you talking to?
Oh, yeah?

Have you had similar experience?
