Bluetooth Tourrets Syndrome

When I land in an airport I normally sit down for a few minutes and catch up on email. Increasingly I find a guy like the one in the picture - who speak on a bluetooth device. For the last fifteen minutes this yahoo screamed into his earpiece telling the entire waiting area about his father's pastrami sandwiches, how most of his family cannot afford things like gas and electricity and a host of other fascinating topics. What is most wonderful about these guys is that they are either a) very hard of hearing or b) so egotistical that they think the rest of us are actually interested in their prattle. I guess this type never learned about discretion or more to the point, manners.
