It is only dinner

I enjoy watching MasterChef. I like MasterChef in all its forms - the celebrity, the professional and the ordinary.  I thinkMichel Roux jr is brilliant, he doesn't play up to the camera at all and I love him a little bit. However the look of terror on the contestants' faces, the self hatred when things go a little bit wrong does wear a bit thin. Has the director told them to look scared? If it was MasterDoctor or Master Surgeon I could understand it- you don't want to be cocking that sort of thing up.
