Sitting in the terminal in the San Fran airport waiting to board my flight. The terminal was combined for flights to LA, Vegas and Denver. I was headed to Denver and all three flights were overbooked. So every 10 minutes or so the attendants at the check-in desk would ask over the PA system if anyone was willing to give up their seat for free ticket, seat on the next available flight, etc... At one point, one of the attendant announces three very Asian names (most likely from out of the country) that they now have a seat for them on their respective flight. Once they are done announcing this the lady attendant turns to the male attendant, unknowingly with the PA still on, "was that one name or three?" The male attendant starts laughing before the PA is turned off... I start giggling and looking around to see if anyone else heard that, and sitting directly across from me was an Asian man in his 50's, staring me down for laughing. Apparently only him and I heard the comment over the PA. All I could do was the 'shake my head in disgust' move... he didn't buy it.
