Absolutely vile. He's pretty proud of himself, isn't he? And this is even after he acknowledges that he was wrong. I want to just shake the little dude and ask if it's his first day in an airport, because waiting an hour in a line is pretty standard, even if it turns out to be pointless. He's an entitled childish brat, and it appears he thinks his readers will applaud. The way he speaks about people is appalling.
This is the shit that Ariana Grande will have to distance herself from. Her star is rising and he's serving as the anvil dragging her down. Her handlers must be apoplectic.
