I would suggest when challenged that they phone my GP Surgery to find out what exemption is in place ;-). Where does Patient Confidentiality and Data Protection come in all this, no one has a right to know my medical history
I disagree. In the current situation I think we should have to prove if we're exempt and why by carrying documentation. Privacy is neither here nor there.
I can see your point, but my concern is what is done to protect that information. Have shop workers been trained in GDPR etc? If you have to show a prescription for a form of medication which makes it clear what condition you have (or, even worse, a letter from your GP saying that you are exempt from wearing a mask due to past sexual abuse), how do you know that this information isn't going to be shared around?
I find it quite scary how many vigilantes are out there, policing mask wearing. Someone was on our local community page yesterday, boasting how he'd 'challenged' two women in Tesco for not wearing masks and reduced them to tears. His justification was that 'if you're too sick to wear a mask, you shouldn't leave home at all'. Which is fine for some - my husband is able to do our shopping - but others don't have the luxury of someone else to run errands for them. And some people have already been shielding at home for 6 months - if they're expected to continue doing so much longer, there's a real risk they will be so institutionalized that they will never be able to rejoin normal society. And I find the lack of concern over that even more worrying - we seem to be turning into the kind of society that Hitler was trying to create - segregation of those who 'don't fit in' is the first step towards eliminating them.
