Every dentist I go to use single-use thin nitril or similar gloves. If they have to use any of the non-sterilisable equipment (like the mouse or kb), they take said glove off before use and put on a new one after.
Common sense would mean that my local butchers and fishmongers would not handover money and manipulate raw meat/fish with the same nitrile gloves and either employ an assistant or use a dedicated machine for that but they do not.
They do here but Norway has a functional balance of regulations and fines for this kind of stuff. Sometimes it’s too strict though but I certainly appreciate it.
