In the early days of the lottery i worked in a kitchen and we had radio 1 on for the lottery results. Our head chef organised the syndicate for people at the restaurant and worked front of house and asked me to write the results down when they came on so he could check them later when having a pint. I found his little folder with all the tickets in, picked a random line and wrote the numbers down jumbled up. Gave him the numbers and left him to it. Later on in the bar i thought i'd killed him. He went pale, started re checking, then started to look around in disbelief. Only when he saw me laughing did he realise and safe to say i had to run fast.
I did feel guilty to be honest, but working in a kitchen in those days was like a warzone for setting people up and taking the piss, plus he was a rag.
