Thankfully I never had this; must be how I look (Asian-American) and the Japanese comic books and novels that I immediately whip out as soon as I sit in my seat. They assume I don't speak English so they leave me alone.
Only when the FA comes around with the drink service in which I reply "Ginger Ale mixed with Cranapple" in perfect English do they realize that I'm American. But by then it's too late.
