Don't sing on TV

I am enjoying the Restaurant. It is almost as good as the Apprentice. I would love to know how the BBC keep finding an endless supply of complete incompetents to star in these shows. The programme itself is a good idea and I have to say that the twins, (I think they are called are Laura and Jess) are surely going to win it and deservedly show. They are bright, attractive and differ from the rest of the contestants in that they appear to use common sense when making a decision. They are in the final 3 against the Scottish bloke who is actually a decent cook and seems a decent guy and his mrs (more of whom later), and also Jeremy and his mrs (who keeps crying at the merest hint of a problem. Knives are dirty - turn on the waterworks. Dropped a bread bun on the floor - breakdown in a flood of tears whilst the hapless Jeremy looks seemingly paralysed. They really should go next but I think this week's episode may have sealed the fate of the Scottish guy and his wife. The task they were set was to delight there customers. They decided that the natural way to do this would be to sing to their customers as they waited for their apple crumbles to be heated up in the microwave. An unusual decision to make especially given that the wife was clearly tone deaf. She absolutely murdered flower of Scotland and looked like she was pushing a number of diners close to the edge of suicide. But they survived if only because the Ghanian couple they were up against decided to delight their customers by giving them a strawberry after they had finished their meal. Where did they get such an off the wall idea from ?
