Open All Hours S2/E7 • St Albert's Day

Arkwright has always told Granville his father was a Hungarian but then a real Hungarian comes into the shop. Could it be him? Arkwright is more concerned that he may be a shop-lifter and hits on a cunning plan to part him from his jacket so that he can search the pockets for evidence. Welcome to the mythical feast day of St. Albert, which Arkwright has invented so that Granville can check the pockets of a foreign visitor who he suspects of shoplifting.
