I have a few friends who work for the airlines in various capacities. When I fly through few certain airports, I never quite know what they'll do. Sometimes I get some pretty nice upgrades, niceties at the airport, a surprise meal on a domestic Y, sometimes strange things attached to my checked luggage.
One of the times there was a pink bra tied to the handle of my suitcase as it came down the conveyor belt. Thankfully, I was taking a taxi at the destination airport and not being picked up by the client.
