"Food while I was in hospital"

I was admitted for a day surgery procedure at Geraldton Hospital this week.  My complaint is not about the care I received which I felt was excellent at all times.   I was asked 3 different times if I had a dietary requirement, one at pre admission, once on the phone and once on the day.   Each time I said vegan.    It was noted.   

After the procedure which didn't finish till after lunch, I was given a tray of ham and cheese sandwiches and jelly and custard and juice.   I asked if they had anything else to eat.  It seemed the staff were sympathetic but said that's all there is to eat.    By that stage I had been fasting over 18 hours and was feeling faint and blood sugar had dropped.    I wasnt allowed to walk to the hospital kiosk to buy something.   Eventually my spouse turned up with a banana to get me through.   

My complaint is if the hospital is not able to provide me with a vegan meal, why did they ask 3 times and noted it.   I feel they could have just said look we can't guarantee that or don't provide plant based options.   I would have happily packed my own food which I really needed for my recovery.    I wasn't expecting anything fancy or difficult anyway.    I feel they could have given me fruit, toast with dairy free spread and Vegemite, hummus and crackers or baked beans on toast.    All items I believe are readily available and easy to prepare.

Also, I wonder about the quality of food provided in a health setting.   I'm sure they have dietitians overseeing the menu, and while I'm not a dietitian I would say that ham, cheese in white bread with a side of sugary custard and jelly is hardly healthy food.
