Maybe it was a "guest list party," that's what some people call a mixer when they plan to have alcohol there.

Any hoo...when everyone is sober and calm, perhaps you should bring it up at chapter that if you all want to have "events" at your house, then everyone has to do their job or the fun gets spoiled. Point out that you'll all been there once so it's "brotherly curtesy" to suck it up and do the assigned door check, beer check, security, etc.
