Ah, yes. So-called "dress codes" must have exceptions. In a Club of which I was once the Chairman of the operating company, a member was a retired naval commander. One day he brought a colleague as a guest, a still-active naval officer dressed in immaculate white naval uniform, perfectly creased trousers, etc, etc. The bartender of the Members' Lounge refused to allow him entry, as a naval uniform, at least in the Australian navy, does not include a tie. Fortunately the duty manager intervened and all was well.
