Not shocked, The Philly airport is filthy. Walking out of the terminals to the bus/taxi stand one must waft through a hundred yards of the stench of hot steamy urine. And the people that work there are outright rude and nasty-and, yes, occasionally racist.
You know your in Philly when that combination of urine, marijuana, and humidity hits you.
Actually, that describes most urban environments these days, plus or minus the humidity.
