This is EXACTLY how my ABF started back to drinking. Drinking on his day off, because well, he didn't have anywhere to go so he thought it was fine. Then it was after work a few beers. Then a few beers mixed with whiskey, then just whiskey. It is a slippery slope and trust me, once they start drinking like that every weekend it becomes an issue. Weekend or not, drinking so much that you fall and injure yourself, get belligerent and act foolish is NOT acceptable. Drinking a few beers with the buddies and relaxing is totally different. This is the behavior of a binge drinker.
