Have you ever wore a face covering for more than a few minutes i have and its really uncomfortable imagine having to wear one for hours on end when there is a huge screen dividing you from customers, they put screens in place to protect them and you if they thought the screen wouldn't protect you they wouldn't have put them in place, you mention Tesco what about fuel stations the ones round here have screens and the employees do not wear a mask when behind them.
Yes, of course I have worn a mask for more than a few minutes, as I hope the vast majority of others do. It's fine. If it's uncomfortable, use a different mask or
get used to it, after all in subtropical Japan they routinely wear masks for extended periods, and have done so for decades, and if they can there, I am sure we can here. Even most athsma suffers can wear masks, even though I've heard some some pathetic people try to use a bleat of "I've got asthma" as an excuse (athsmatics can see athsma UK for guidance; if they had very bad athsma, guess what, they would certainly not want to expose themselves to the possibility of being infected with SARS-CoV-2).
The screen is largely an irrelevance when non-socially distanced employees are behind it, who also work on the shop floor itself. The screen's to stop staff-customer (either way) transmission, just as masks are. Masks are NOT designed primarily to protect the wearer, that's a very minor second function, I wish people had all understood that by now after all this time.
If in fuel stations people work socially distanced or solo, that's fine. If not, exactly the same goes for employees there, or anywhere else for that matter.
Disgraceful.
Again:
People should not just be doing what they are told is the minimum necessary, they should be doing everything that they can.
Over a thousand gone before their time again today, I see. The people who "won't" do most certainly bear some responsibility.
