I agree to some extent and I am often surprised to see that the Stn gym isn't run by Serco like the gyms outside the wire. But some RAF sports are totally funded by non-public money. The only support they get is the use of a building and all members conducting the activity are off-duty either giving their time and expertise for free or they are paying for the sport at a non-profit rate (that normally works out to be 30-50% cheaper than going to a civvy sports provider).
RAF Sports Assocs should come at no cost to the Tax Payer, but even then should offer the opportunity to the Service person to conduct that sporting activity at the lowest possible cost to the Service individual paying for it from their own funds. That is the aim of most RAF Sports Assocs and Clubs.
