...you've trained the young unemployed; you've done your thing in schools; you've opened restaurants and written books. Now, would you please turn your attention to hospitals?
Hospital food is disgusting. Every hospital I've ever been connected with serves horrible food. I know they have a tight budget, but (for example) do they really have to serve soup at every meal? How many people have soup every day before their main meal? It's not necessary. Plus, have you ever tried to consume soup in bed? If you're flat on your back (as I was, for five weeks) the soup ends up in your ears. Trust me. I know. If you're old or frail or just ill, conveying soup from bowl to mouth without incident is a hazardous undertaking. Omit the soup.
Then, meals could at least be made to look atractive. If you don't know what you requested, the odds are you won't be able to identify it when it arrives. One patient of mine (admittedly, years ago, but things haven't changed much) said, when presented with his meal: "I've often trodden in it, but no-one's ever expected me to eat it." Nuff said.
I could go on. And on. But I won't, because you get the picture, and I know you can do what hospital caterers have long failed to; feed people edible food on a budget.
