A long list, and the benefit of the doubt
Who is on the list
Health, care, education, emergency services, public transport, refuse, and anybody working in a food shop. Full list on the page.
If you are not sure
You qualify. That is the actual rule rather than a friendly gesture, and staff are told to apply it that way.
Why so broad
Drawing a line somewhere sensible turned out to be impossible. A broad line and some slippage is better than a defensible one and arguments.
