While I agree with everyone regarding the post from YL, here was an incident about 6 years back on a DL 757 out of ATL. There were about 3 or 4 jumpseaters ahead of me and I was the last one to request it. I had ran to get this flight and luckily was able to get on with a seat in the back. I had left my flight kit by the galley behind the first class and usually take my passport, license and medical with me up front. This time I had forgotten that since they were in a hurry to get us boarded. Anyway, I proceed up front behind a World guy and the captain asks me for everything. I tell him that I forgot it in the flight kit and will go back and get it. He decides to follow me out to the galley and hovers over me while I'm taking all the required documentation out. As I hand him all the material, he proceeds to say out loud "Well someone stole a uniform and I wanted to make sure it wasn't you." Needless to say this statement and my brown skin got me a lot of stares from the passengers who had heard it. The flight attendant was watching the whole thing and said that this guy had been hard to deal with the whole trip.
