South Coast here. I wore a mask for the first time in a shop today, I didn't really pay close attention but I reckon approx 50/50 in a big sainsburys this afternoon.
As to why not wear a mask. I'll try and be honest. I've really struggled with the idea, it feels so alien to me. It's not about not being told what to do, for me anyway.
Asian students wear masks a lot of the time (I'm in a university town). I always think it looks odd and dehumanising, but that's their choice and I have no problem with it.
Muslim women wear face coverings. Again, their / their husband or religions choice. Not for me.
So for me to join the ranks of 'people who wear masks' just feels odd. It's never been something normal for me. Also I feel naively complacent, I'm youngish, healthy, and I very much doubt I'll be hit hard by covid. If I was at all sniffly a) I'd stay home and b) I'd be happy to wear a mask to protect others, but since I'm not coughing I don't feel there is much benefit.
However I can see the writing on the wall and I assume it will become compulsory soon so I've started wearing a mask, just to see how it feels.
I've concluded that it's horrible wiyth glasses, much better with contact lenses. And it's fine. So I'll probably wear one for the foreseeable when I rember to bring one out.
It almost felt like an admission of failure initially, but now more and more people are wearing them it feels more and more OK to me
