I agree that certain clubs must have rules, such as advanced Bridge. Open cards means open cards. If you have your own group, and don't want to include others, then go play at your own homes. If you can't fit your group, add-on a room. How many times have you gone to a Club or other activities, only to find the seats saved, or find yourself totally ignored by the group. Not always the friendliest place. The person in charge should be responsible for making new people feel welcome. I know it is a thankless job, but you volunteered to do it, so do it.
