Pardon The Expression (Season 2 - Ep.5) The Annual Stocktaking (1966)

First Broadcast: 7th May 1966.

Plot (From Corriepedia):
Leonard Swindley keeps the entire store up all night doing the annual stocktaking. The next day he visits the travel agents to book the tickets for Mr. Hunt's annual vacation in Spain and then almost causes Mr. Hunt to crash his car when he steps into the road in front of him. His boss is not in a good mood as a result and even less so when Swindley appears to have lost the stocktaking results which he took home to collate and which Sir Charles Dobson is eagerly awaiting on the other end of the phone. Swindley goes back over in his own mind where he could have left them and realises that they may have been put out with the rubbish but a visit to the local tip results in him being covered in the latest delivery of household waste and in the binmen threatening a strike when they suspect him of being a council snooper. Hunt forces Swindley to ring Head Office in London and confess to the result when, at the last minute, the travel agents turn up at the store with the stocktake which he left at their shop. All would seem well but there is another more alarming puzzle - what has Swindley done with Hunt's holiday tickets...?
