To that end I now provide the first of a series of the embarrassing moments from my past that I deem to be repeatable.
For those of you who have never sampled the delights of this sketch it can be found here on YouTube.
Mr Cleese approached the till and explained that he was in the area and decided that what he fancied was a book and that he had spied our emporium of the literary arts and hurried in. He didn't really but if he had at least I would have been forewarned.
He requested a book, I'm not going to say the title because the confidence between a customer and a bookseller is a sacred trust, let's just say it was a perfectly reasonable book to ask for. I looked it up on the computer and found that we didn't have it in stock. Regretfully I informed Mr Cleese of our deficiency and he said "No matter," and requested a second book.
We didn't have that either and I think you all know where this is going. By the fourth non-available book I was just waiting for the question - "Are you sure that this a bookshop?" to which I would have been forced, by statute(1), to reply; "Yes sir, finest in the country." I dread to think what would have happened next.
Fortunately I was saved by the intervention of my manageress who took over at the till and allowed me to flee at the first opportunity.
