Poor Customer service

I visited the gym with my kids and wife (who is not a member). Expecting to have a work out while my wife watched the kids, both under 14. Was told by the manager that if I as the main member was there my wife was not allowed in. Even after explaining to him that my wife was not using the facility but merely looking after kids. He would not except any leway \this is the rules". Had to leave the gym with no swimming for the kids or me getting my workout. Surely there should be some common sense in dealing with customers. His explanation was that it was to prevent overcrowding at the gym. Today is the 16 December"
