There are so many foods one person would find appropriate that another will find revolting...
And often very few options at a hospital, as to whats open, available etc.
Then of course the person eating might need to factor in not just what they like/dislike from the available options but any health issues they have.
So 'will this food upset someone else around here' is bottom of the list of considerations!
One of my local hospitals, after about 6pm, the nearest, cheapest options are mcdonalds or KFC (you can up that to Dominoes or chinese if you want to pay a higher delivery cost). The hospitals canteen only runs til 6pm, after that there is only the food pre-ordered for those on wards and a vending machine with crisps/chocolate/biscuits.
The bigger hospital is slightly better, the shop is open til 5, canteen til 6 and Cafe Nero til 8pm. There are vending machines with hot soup, and hot sausage rolls/pasties (if they work! Often they're out of order) - these all absolutely stink... Vending machines with chocolate/crisps, and a coke machine.
Again beyond that, if you've not got a pre-ordered meal from the kitchen, as an in-patient, you are shit out of luck and it's takeaways or go hungry.
Sorry, I think YABU, people do have to eat, and these days you can spend a huge amount of time waiting around.
