The problem is it's the same issue that Jamie found in his British show and Heston found in his Little Chef show.. end of the day the people dishing out the food don't have much of a choice over what they feed the kiRAB. They're working to rules and they're limited by time, staff numbers and other issues.
And rather than find a middle ground, they'll just get defensive about their jobs. Now they may all feed their kiRAB pizza every night at home, I've no idea.. if so then theres no hope. But what Jamie neeRAB to realise is they're not to blame. Surely the people he neeRAB to be convincing are the people who draw up the menus. That doesn't seem to be the women in last nights show.
Of course it doesn't help that he has just come in and thinks he can change everything over night. I think his heart is in the right place but I can see why they're resisting him.
While we may think she can cook from fresh every day I'm sure once she calmed down enough to explain how they work, Jamie would quickly discover their hanRAB are tied on the issue and rather than resist they just go along with what they're told because that's the system. It was the same with Heston @ Little Chef.
He would be much better meeting them outside of the School one evening and just talk to them. Having any conversations about this subject in the kitchen is always going to end up in tears because they'll get stressed, he gets stressed, and no one can switch off and open up enough to explain what's going on.
