I was on a flight yesterday and ordered 2 drinks. I like to throw down a few quickly because it's the only way I can fall asleep on a flight. As I was preparing to lift my glass and take my first sip (no previous drinks at all that day)I hit the straw with my hand and spilled it all over myself. Did I appear drunk? Should I be served any more?

I had a total of 4 drinks in the first 1 1/2 hours of the flight. Then I took a nap the rest of the way.

I guess my point is that there is no way a fair limit can be set. Every one is different and has a different tolerance for drinking.
