There are some people who may get a little overexcited about the open bar at your friends’ wedding.  As long as it is not their close family member or best friend, the bride and groom do not deserve to be concerned with the barfing bridesmaid or groping groomsman on their big day.  If you happen to notice that one of the guests is walking a little funny or making others feel uncomfortable, the first thing you should do is get them out.  Not necessarily out of the wedding for good, but maybe into another room or hallway for a little while.  They should also get some food in their stomach and keep hydrated—with water—two things that are pretty easy to accomplish at a fully catered reception.  If they are not yet inebriated to the point of an intervention, don’t feel bad asking the bartender to keep an eye on him or her or even cut him off from the bar.  They have seen their share of hammered people and know when to take action (their thrill of the night and big tip opportunity too!).  In all honesty, it is likely that you will see one or two cases of booze-abuse at most weddings you attend.  And although they will make for a few good laughs in the video, the bride and groom would really appreciate your effort to prevent them from embarrassing themselves and others, getting sick, and especially driving home.
