The Prisoner might not have been a club member, but he was certainly taken to lunch by Sir Charles at his club, where they had their favourite dish - jugged hare, which was on the menu.
No, I can't really see the Prisoner as being a member of any club. And as for Sir Charles's club, well that's a gentleman’s club no doubt. The kind of club which is for gentlemen only, meaning no women are allowed over the threshold, allowing men to get away from their wives, mothers, and even daughters! Perhaps the kind of club filled with old doddering men, perhaps men once of power, who have lunch then spend the rest of the day in their favourite chair asleep behind a newspaper! Not the kind of club I think for the Prisoner, if indeed the Prisoner is actually a member of any club in the first place, which somehow I doubt. However he is quite happy to go to a club as a guest from time to time.
I used to be a club member for several years, but then the time came when I resigned my subscription!
Be seeing you.
