Jim - quite agree that's its hard enough to run a club and all credit to those who do it.
When I'm on holiday I like to visit new clubs - and sometimes we get asked to play and sometimes not. Mostly we are made very welcome. We don't complain - just not go back to some. Its loosing the non complainers that may damage a club if enough people do the same. One slot for a duo may be a reason.
