Was the server "Breanna" spouting off with 99% vs 1% crap to the banker, or within earshot? Was she wearing some kind of disrespectful 1% garb or button typical of the class warfare crowd?
The story doesn't say, and it IS the HuffPo, which makes it automatically suspect.
The "leaker" seems without a doubt to have a 99%er agenda, characterizing the person who wrote the note and left the small tip using the language of class warfare typical of the 99%er class warfare crowd.
Without further information, there is no possible way to know whether the tipper is an asshat as described, or if he was responding to something that happened.
I was at a fine restaurant several years ago when I still had hair down to my belt. The waiter assumed because I was long haired and tattooed that he should be comfortable talking to me about drugs and partying. He received zero tip on a $250 tab, and a note telling him he was a loser.
People didn't have cameras on their phones those few short years ago, but if they did, It would have been quite easy for someone to snap a photo and make me look like an asshat.
My policy is to give a 20% tip as a default, a better tip for excellent service above and beyond the call of duty, 15% if something about the service was not up to snuff, and to allow some grace before I start thinking about reducing the tip any further. So I don't outright defend the actions of this banker. But I certainly do call into question whether we have the facts. Given the screed by the "leaker" that repeats the class warfare rhetoric of the 99%ers by rote, it would seem to me that this is an agenda-driven attack, and that we do not have all the facts.
