Threatened to sue my (UK) optician for refusing to give me an eye test for being mask exempt - and he just called to say he "just happens to be in the surgery today, and would I like to come and get tested?"
Finding this helped: Optometry Today
Face masks ‘not mandatory’ for patients in optical practices, according to new government regulations
FIGHT - DO NOT COMPLY.
Winning - God be praised!
We have exemptions in the UK, refusing to allow them is illegal so I wasn't breaking any rules - they were.
I'd hold on to your driver's license though; don't do anything rash - you might regret it.
