I agree, but the one thing missing is why the passenger thought he needed to make a phone call. For all we know, he was trying to call his lawyer for advice.
I don't think that excuses him, but it was a strange reaction. I suspect that there was plenty of @sshattery going on from all three sides: the passenger, the flight crew, and all the other passengers.
A phonecall??? Sorry... he needed to get his sorry @ss off the plane and leave the rest of the passengers alone to go on about their way.
A phonecall is not a right. Hell, it only became ~possible~ a few years ago. That doesn’t make it more important than the rest of the flight.
God forbid he call an attorney while being thrown off a plane for having a bagel in a bag.My grandmother must be a threat with her tuna sandwiches because she would smack the crap out of you if you touched her food and tell you to GET LOST!
