The guy walking back and forth arguing on his cell phone was hilarious. But the real problem with smart phones is how thumbing has transcended verbal and face to face communication. JUST WALK AWAY when in the middle of a conversation someone rejects you for their pocket going off. JUST WALK AWAY when it happens. It is not only rude, but 99% of the time the interruption is total crap. And I am beginning to think that any communication done by thumb can be done not at all with no ill effect.
