A colleague once saw me heading to a post box with a pile of 10 envelopes. (In the days of postal entries - I only do free online entries now.) He asked what they were and I told him that I was entering competitions and this was the latest batch of entries.
Colleague: "It's all a fix - nobody ever wins those, or if somebody does it will be a mate of one of the judges!"
I won a synthesiser worth £1,800, a piece of software worth £35 and a pair of cycling sunglasses worth £50!
I have won a few other bits and bobs over the years.
