What's so weird about that? Even if you get booted you still have to pay your tab, or you could get arrested.I agree with the OP... But... Last paragraph:
The Happiest Hour denied that Piatek had been removed in the first place, stating Piatek “was sufficiently pleased with his service at the bar [and] that he added” a $36 tip onto the $186 tab, according to The New York Post. The bar owners suggest Piatek’s lawsuit was a “publicity stunt.”
That's... Weird.
And you certainly don't punish the waitress by not tipping just because the owner is a TDS afflicted moron. You have sympathy for her.
