The most used piece of kit in my kitchen is my saucepan. I use it every morning to cook my porridge in. The least used piece of equipment? I'd say a food mixer. I've never used it I don't really know what they're for.
When I was 19 I made my first good week's pay as a club musician. It was enough money for me to quit my job at the factory and still pay the rent and buy some food. I freaked.
