Right, I want to share my experience of NOT wearing a mask in a South Cambs Tesco. (Spoiler alert: it's a good one).
For the record - I am exempt.
I rocked up to the door, no security. Walked straight in and got on with my shop. There were plenty of people in there (almost all masked, but I didn't see everyone, so can't confirm).
There were very polite people doing their shopping, going about their business. I was very polite as I always am, letting people through and respecting their space.
It was VERY quiet, compared to a normal shop - I suspect it's because people don't speak with the masks on.
The staff were absolutely fine; not all were masked. The ones that weren't, were of ALL ages (young and old). We had a chat with some staff, who were lovely (but we know them anyway).
I admit, I was apprehensive at first, but I just meditated throughout the entire shop and was fine.
You ALL need to get out, get on and live your life (respectfully, lovingly and peacefully). Before you know it, you'll be at the end of your life and you'll regret it.
I hope this great experience, will give you the confidence and encourage all you exempt people to stand up and get on with things, in a positive way; Lord knows we need it.
Take care one and all.
