Not due to a job but things I have experienced buying fast food.
Server who dropped the mayo - er sort of looked like the thing you use to put bathroom sealant on - on the floor, picked it up and was about to use it to put mayo on my burger.
She wasn't too happy when I told her didn't want that mayo.
McDonalds, a server emptied a bin and then went to take a couple of orders out tot he car park. I told her she should wash her hands, apparently she didn't because, "the bag is sanitised".
I once had gastro enteritis following a trip to Pizza Hut and the cinema.
When I was able to use the phone I called the cinema where I had bought ice-cream and Pizza Hut.
The cinema was not interested and didn't understand why I called.
Pizza Hut said straight away they needed to get a manager. The manger came on, identified herself by name and obviously had a check list to go through asking about exactly what I had eaten and when and had I seen a doctor etc etc.
I don't know what their hygiene practices were / are but they obviously take possible food poisoning seriously.

Private schools can employ who they want, you don't have to be qualified teacher to teach in them.
Private hospitals are not subject to the same standards as the NHS. They don't need to employ qualified people e.g. overnight there may be no doctor or qualified nurse on duty.
I worked for one for a couple of years, and it was a good one that did employ qualified nursing staff for every shift.
But overnight the only doctor on call was an obstetrician, who was provided by the NHS.
I have only met one Dr who only had private patients.
If you do want to 'go private' your best / safest place is a private wing / ward at an NHS hospital.
