With our leagues being played in a traveling league system to many small time bars where you visit their local drinkers, many situations come up. At times, this situation comes up and nicely let him know this is a pool league night, not a tournament, but, not there to just play around either, if he continues, go right to the bar and ask who is in charge and that you request it stopped. The bar person can try or just call the cops. The nice thing is, you inform the person, then inform the bar, maybe have to inform the bar person twice, but, when the drunk starts being agressive against the bar person, then all the fun can take place, all the pool players then can come to the aid of the bar worker and they are most happy. A word to the wise though: when the cops come in, stop using your break cues butt end as it does not look good to keep beating his butt with the cops looking down at you. ok, well, you might just want to pass on a code word to both teams when a person starts acting up and all players from both teams come forward to let the person know this is a league night and his influence is not appreciated. Most drunks don't like 10 people chiming in at them at once. Also remember, most bars sell their logo t-shirts, grab one of these off the hangers and put a cue ball in it. One of these to a knee cap will usually halt most advancements of big big guys, especially having 10 of those things circling in the air. Geesh, I guess I go back many many years in pools. Maybe the best thing is to disregard most everything I have said and handle it the way you did, let the bar tender handle it with dialing 911, just don't forget what I have said if your backed into a corner.
