Pretty cute little episode. But when you are getting cut off in bars and getting arrested on layovers folks. I'd say that there is a pretty good chance it might be time to get some help. Whether he knows it or not this guy has a drinking problem.
At what point does a "few" beers on a layover become a problem? DUI, PI arrests, fights, getting kicked out of bars, making it on the nightly news. These are all things that you could call a clue.
