Me, not the most stupidest thing but probably the most ridiculous.....I was managing a Chaufeur company at Mcr Airport and the boss had sent me off to a new potential client to seal the deal, I did and got a pat on the back. A few weeks later I was sat in the office, work done, all drivers and cars sorted, flights incoming and outgoing all done so I put my feet up. The phone rang, a rather irate customer telling me he had a client at T1 and why wasn't there a car for him. I told him I'd check and sort it out. In the meanwhile he's asked for the drivers number, there was only me....... There was only one thing for it so I ran like the wind to my car, one of the fleet of decent Mercs and set off. I'd given him my number and it rang as I'm driving down Shadowmoss rd. I was thinking on my feet here as it was a brand new but decent client and worth a bit.I wound the window down and put on a ridiculous yorkshire accent whilst speaking to the guy who had just phoned the office number and now thought he was speaking to a completely different guy altogether, hoping the wind would disguise my voice and told him I was on my way but had had a puncture. I stopped on the approach to T1 and wiped my hands round the wheel, got back in and went to meet the client and apologised for being late but as you can see I'd just changed the wheel and need to clean my hands.
The main client saw straight through this and phoned my boss mentioning the most ridiculous Yorkshire accent he'd ever heard and me driving with the window down didn't convince him either....Never heard from them after that.
