(R.C. is serving a woman with a toilet roll. He is not too bright.)"
The two main actors are Ronald ("Ronnie") Balfour Corbett, who is one of the finest British sketch comedians, and Ronnie Barker. Corbett plays the shopkeeper and Barker is the customer. The acquired title of the sketch is "Fork Handles" or "Four Candles". It's under this title that you can find the video clip in the Internet. (My thanks to John Maidment for drawing my attention to it).
The sketch is phonetically interesting, and I should like to make some comments on the sketch in future blog entries.
