I'm dealing with this same issue. I've always got home brew and regional craft beers (Red Hook) at the house. And when family comes over, I always get a half-rack of a BMC beer, because I know that's what my two son-in-laws drink at there own home. The problem is they always grab a Red Hook, or a pour off the kegerator.
And when I go to their house, all they offer me is Icehouse. And if I bring my own Red Hook, they start drinking that.
For the Seahawk game this past Monday night, I hid the Redhook in one of my keg storage keezers. And I just went on got one for myself when I wanted one. I think they are starting to "get the message."
