You already know that you'll never be a member - you aren't rich enough or posh enough. Or entitled enough - with or without actual title. Enobled enough.
The plot of On Her Majesty's Secret Service hinges on Blofeld being not just a supervillain, but a supervillain entitled enough to expect a peerage.

Coutts is like posh banking Wonderland. Ghastly? We're all ghastly here.
