None unless they contravene the LOTG.....or they are clearly a danger to themselves or their opponents.
Let's be realistic here.....every Sunday morning there are always players who have come from a big night out and would undoubtedly be over the drink drive limit.....do you 'take action' with them?
If I see a team with alcohol on the touchline, it gets reported to the league, as per league requests. If I feel it has contributed to an incident of misconduct it will get mentioned in the relevant report.
But I'm not doing anything specific just because I catch a whiff of booze from a player.
