Okay, to the point: People who stand in public places talking loudly on cell phones are arrogant jackasses. This is not new.
However, people who stand in public places talking loudly on cell phones via "hands-free" headsets come off as *clinically insane* arrogant jackasses.
You - standing in the doorway of the corner store subjecting everyone within earshot to the mundane details of your private life or business dealings, perhaps pacing a little while belting it out - you have never looked more foolish in your life; in addition, the side of your conversation we can hear is just plain annoying. We despise you.
You - e-boy in the raver pants - we don't want to hear your observation that "that girl was hot." You - frowning ding-dong in the suit with the legal pad - do not tax us with your whine about "the client." Again, we despise you. You look like an idiot.
Can we get the Phonebashing folks to move to San Francisco? Then again, I probably look like an idiot right now - I'm writing this outside Tully's at Jackson and Fillmore. They probably despise me. I may well look like an arrogant jackass. I wonder if these guys have an outlet I can plug into...
