Mask wearing seems to have dropped down to roughly 10-20% on public transport and in shops now.
I don't bother to wear a mask in shops that are spacious and/or quiet. I do my Big Shop in a supermarket as soon as it opens at 0730, when there are only a dozen or so other customers there. Were I to go there later in the day, I would wear a mask.
Just had a letter from SpecSavers reminding me it's time for my annual check-up - before booking an appointment, I'll be checking what precautions they're still taking, given the test is very face-to-face.
For the test, I'll be making a five-minute train journey into town and expect there to be very few other passengers, so shan't wear a mask. If I return when it's busier I shall.
I had my fourth jab two weeks ago, so reckon to have good immunity for a while. And hopefully infections will decrease over the summer months. Come autumn though ...
