LadyWee He doesn't have a full set of lungs, one of them is only partially useable, and he has difficulty breathing a full lungful and a bit without a mask, even when just walking. Masks, to be effective, need to fit closely to the face. Of course it restricts his breathing, masks, restrict anyone's breathing, I am always conscious of it when wearing a mask - and I have no respiratory problems.
He has tried very hard to wear a mask, but can just about manage it for a short time if sitting. Wearing one in the surgery was for a couple of minutes, if that. The vaccination area was a room with direct access to the outside and each person only went in once the nurse was ready to jab, so he was inside, pulled his sleeve up, was vaccinated and was straight out, if they were as quick and as efficient as the centre where I had my third jab, he would have been in and out in about a minute. There was no sitting provision for 15 minutes after the jab.
Peasblossom Someone seeing someone at a distance of 15 feet and running away shouting 'I am going to get COVID, I am going to get COVID' is not being in a queue where someone becomes anxious and leaves
I think if someone was as anxious as this lady, then she would perhaps have been wiser to have someone with her. In her circumstances I would certainly not have wanted to be outside without someone with me. The chances of meeting someone unmasked, or, worse still having someone unmasked breaching the social distance rules is so high, it would be a risk I wouldn't want to take.
When DH first came out of hospital, I went everywhere with him, because he got easily distressed if things didn't go as intended. Now he is more robust and he was able to deal with this incident, although it still caused him internal turmoil.
