Didn't see this posted anywhere else, but anyone flying to/from/through PHL should be aware that pretty much every restaurant, convenience store, et cetera at PHL now imposes a 3% employee wage and benefit fee on each transaction. I didn't see this disclosed on any menus or at Hudson News, but read more about it below after seeing the charges on my receipts...
