In my former life, I was a lecturer in hotel and catering management. It was a great job, if it hadn't been for the students! Joking of course, it was the staff that were the problem. I worked in a recording studio and touched the hem of the garment of some of our pop glitterati... I did of course, wash my hands afterwards. Also worked with blind people. A rewarding and fulfilling experience and I was a builders mate, on a large housing development.
