Oh I have a better one than that. I got sacked from a job for not using a new piece of equipment that was signed off on. When at the appeal I just said I couldn't have been signed off on said machine they asked why. The simple answer was I was in our new York branch at the time and I could not of possibly been in London to receive the training. The manager who sacked me even produced a document that said I had attended the training course. Of course they asked when was the training course in relation to me bring sacked........I answered the week before I was sacked, it was my first day back at work in the UK!
