"I'm not usually a prankster, but I did get one guy good. He was known as a major prankster. He had this fancy car that he mentioned to me at an earlier contract, but he hadn't told me what it was because he was trying to keep his contract prices secret and the car would have had people curious.
On the current contract, he would usually come to work in beat up Land Rover, and as it was night shift, if he parked in the roadway near the worksite gates, his habit was to leave side lights on. One night, I saw a Triumph Stag parked with side lights on. At the time, it was considered a fairly fancy car. On the way down to the platform (we were doing renovations to the platforms at Kensington), I pondered on what to do if he was there. I had checked there was no sign of the Land Rover, so that would mean the Triumph was almost certainly his.
As I spotted him on the platform, moving a heavy paving slab, the idea came to me. Walking up to him, I said, 'Hi Kevin, you didn't park your Land Rover round the back, did you?'
'Err, no I didn't,' and the way he reacted to my mention of the Land Rover made me pretty certain the car was his.
'Oh good, if you had done, you probably wouldn't be able to get it out any time soon, some idiot came out of the Tiara hotel across the way, and he plowed his jag into a Triumph Stag right outside the gates, never seen such a tangled mess.'
He goes white as a sheet, and almost drops the paving slab in his hurry to put it down safe, and starts hurrying away. Before he got off the platform, I couldn't hold the laughter any longer, he realized he'd been had and came back. He was a bit cheesed off, but was a good enough sport that he could take a joke as well as dish them out. He then explained why my joke caused such an strong reaction. In the year he had the car, it had spent half that time being repaired due to two incidents, one while sitting at a red light, and once while parked. And he had just got it back from the last repair! Lucky timing for my joke."
