My thanks to people who have chimed in over the drinking issue overnight. I probably have some significant blind spots on this issue, given that I have no taste for alcohol and therefore almost never serve it at parties I host. Although I do remember a MythAdventures Fan Club party I was hosting where some loud and pretty lubricated people came in demanding, "Where's the beer!"
I said, "We don't have any." They made loud noises of dissatisfaction. I asked them, "Is there any chance you'd join the club if we served beer,"
They said, "Hell, no!"
I asked, as reasonably as I could, "Then why should we bother serving it?" They had no answer to that and left.
