Allan, I'd tell the prez. Perhaps he could take this guy to school about "how we treat our guests" or at least he'd become aware of a potential problem in the group. Knowing him a little, I'd say he'd like to know.

I've always been amazed at how willing groups are to part with their money one day and completely unwilling the next. Amazed, but not surprised.

Which brings me to this. A guy once suggested a policy to me that I'm trying to follow. Criticize me if you want, but it helps my sanity. "Never go to an indoor meeting about an outdoor hobby."
