I was flying the other day and some fat dude showed up in a worn-out wifebeater, basketball shorts leaving his pink (actually pink!) sore-ridden Steve King melon calves exposed, and flip flops. Didn't get a second look from any FA. But a hell of lot of people were clearly hoping he just kept walking down the aisle as he approached their row...
Guess us white guys really get a hall pass on the appropriate clothing thing.
