I don't see why all the antagonism towards the OP's observation. He didn't say that everyone who travels for work is an alcoholic, just that from his observation they usually are. From my observation I certainly wouldn't say that frequent travelers usually have a problem with alcohol, I'd say that such individuals are certainly in the minority. I don't think alcohol is the issue here. People can drink as much as they want, and it has no effect on me, as long as they remain considerate of those around them.
