Timbrell Recreation Centre, he didn't realize just how seriously staff took that "females only" stuff. Chris, whose last name wasn't reported by local media, said that when the two arrived at the center he was informed he would not be allowed to watch the lessons. He said that nothing on the city's website, where he'd signed up for the lessons, mentioned that. City aquatics director Anne Jackson said the females-only classes are designed to accomodate the "cultural and religious practices and requirements" of some residents. Don't worry, the city also offers males-only classes, and the mothers of boys who take them aren't allowed to watch.
