"heart surgery and after care"

My husband had open heart surgery and I cannot fault any of his care. I believe his surgeon to have been extremely skilled. My husband has recovered very quickly after his operation and was walking uphill to his GP's surgery a day after he was discharged. The nurses too were very skilled and kind. However, when he returned for his six week check up, I was astonished to see a large vending machine in the cardiac outpatients' department which had four shelves of crisps or similar products and two of chocolate bars. This was all there was on offer except for tea/coffee and hot chocolate.
