Dudes, don't get so worked up over it. If you're going shopping then you're only going to be in the shops for a relatively short period of time (unless you're one of those weirdo's who spends 15 minutes in every aisle picking up every third item and reading the whole of the packaging). All you have to do is make a small effort and wear some kind of face covering just so you're complying with the new rules. This can be a scarf or anything as long as you're obviously not taking the mickey. I personally use one of those Buff snood/scarf things that people use for hiking etc. Very thin material that sits around your neck usually but can quickly be pulled up to cover the mouth/nose/face. You can then use it in the winter when it's cold etc so you're not just throwing your money away each time you throw away a disposable mask. No decent place is going to give you any grief as long as you genuinely show that you're trying to stick to the rules. https://www.gooutdoors.co.uk/mens/br:buff/ (an example of the scarves/snoods I wear) It will be hard to enforce anyway as many people will just say that they can't wear one due to a hidden disability and say they have no documentation with them. Not many security staff will be able to turn people away if they just lie about it. I can see half of the population suddenly developing a condition. I just simply don't see the problem with putting a covering over your face whilst you spend minutes shopping unless you genuinely have a health reason not to. So many babies around these days. Much more important wars to fight with the government than not wanting to wear a mask for a few minutes every couple of days.
