If you are not happy then follow BT's example and don't wear one. You'll be fine and no action will be taken.
At what point do you consider the risk will have diminished sufficiently 59 ? The last ONS figure I saw said just 1 person in 2,000 had the virus, so the likelihood of you encountering anyone with it on a shopping trip is remote, and should you encounter the 1 in 2,000 as long as you keep more than one meter away he/she cannot pass it on. So the risk of actually catching it while out shopping is virtually non-existent right now, but this isn't sufficient for you, so at what point does it become sufficient ?

I am not happy about wearing one, but I will wear one when I'm required to, and already have done, twice in the optician's and once in the newsagents.
