I know the feeling.
I once stayed at the Berkley and went down to the lounge on Sunday morning to enjoy the Sunday Times and a morning coffee. No one else was in the room. I was dressed in a cashmere turtleneck sweater, Burberry double breasted blazer, grey wool trousers and polished bespoke shoes. I asked an attendant for a pot of coffee and was told he could not serve me because I was not properly dressed. A tie was required. I asked where in the public rooms I could enjoy my Sunday newspaper as I was dressed and the answer was "nowhere sir".
Within a hour I was reading my Times and enjoying my coffee at the Four Seasons.
