Way back in the 80's I was on a biz trip to Mexico. I was in the last row in the window seat (was not elite back then) with a very large Spanish couple next to me. It was a very rough ride and everyone started upchucking. I don't get sick in airplanes (I'm a private pilot and am used to a few bumps) but most of the plane was barfing. I asked the FA for a couple of double scotches to get me through the storm. She looked at me and saw what was going on and handed me about 6-7 little bottles and 3 cups of ice and said "Have a good time".

Once one person started barfing, the rest just got into the scene. The smell was unbelievable. I had to wash all of my clothes in Mexico City to remove the stench.
