Reminds me of some fun we had whilst in the Service…
Whilst working at an outdoor centre in the Scottish Highlands we would regularly try to sneak some useless item into the other instructors’ rucsacs with the hope that they’d only discover it whilst on the hill. To this end on separate occasions I discovered a pot plant, a clothes brush and a wheel brace whilst journeying through the mountains, none of which were particularly welcome additions to my packed weight. Not wanting to miss out, amongst other items I managed to sneak an old fashioned telephone (the sort with the handset on a curly wire and the numbered disc with holes in it) into a colleague’s rucsac; he wasn’t happy as our ones in the UK were particularly bulky!
This practice became widespread throughout the Service outdoor centres but my mate finally got his comeuppance. He’d been targeting a Marine who joined in at first but then became grumpy at discovering another useless item that he’d just carried for several miles. To get his own back he waited until my friend was away on a course and then packaged a large dictionary and thesaurus and posted it to my mate’s home address without paying for the postage. My mate’s wife, a fearsome type, received a note from the post office a few days later that said there was parcel needed to be picked up from the post office in her village, which she duly did. After parting with a significant some of money she opened the package to discover the two very large books with the Service stamp inside them showing that they were from the centre. Knowing her husband to be a practical joker she realised what had happened and gave my mate hell when he returned from his course. The moral here is, I guess, don’t mess with a Marine.
