I had to fly to Cochabamba Bolivia for a work meeting years ago. The flight connected in Miami before going on to LaPaz and then onward. I had about 4 hours to kill in Miami airport before the next leg so I sat down at a bar. They had a special running on double gin and tonics. Uh oh! I barely recall getting to my seat and falling asleep. When we landed in LaPaz, I had to find my next connection. Given the altitude and my severe hangover, my head felt like it was about to explode. No idea how I made it all the way in one piece.
Lesson learned...back away slowly from airport pub specials, as no good will come of it. I even left my carryon in the overhead bin and realized it when an airport worker came out of some back room and said "mister, is this yours?" as i was sleep walking to the next gate. Oh boy.
