If I must use one, I shall make use of one of Marge's old bras, but only the left cup.

Good idea JBR! You don't want to look like a right t*t!

God love him, funny man.

I am now wondering if JBR is a 'cup half full', or a 'cup half empty' man? Although I guess
that very much depends on the numerical and alphabetical sizing of said item.

I have seen hardly any shop workers wearing masks. They lurk about blocking aisles, hanging about and barging past.
They are mixing with folk all day. They don't sanitise hands between customers either.

Environment Secretary George Eustice told BBC Breakfast the new mandatory rule for face coverings in shops does not apply to retail staff.

New measures meaning people in England must wear face coverings in shops will be "nigh-on impossible" for police to enforce, a union boss has said.

Metropolitan Police Federation chairman Ken Marsh said shopkeepers would need to "step up to the plate" and take responsibility for ensuring customers wear masks.

"They can quite easily put signs up on their doors [saying] 'no mask on, no entry, this is private property'," he said.

"That's the first point we need to get across because this cannot all be laid on the shoulders of the police yet again. The second point is it will be nigh-on impossible for enforcement because you won't have a police officer on every shop door because there isn't enough of us."

Mr Marsh added if shopkeepers called the police to ask them to enforce the rules, the person could "just walk away" as shop staff had no right to detain them.

"We'll be driving around and around London looking for people who aren't wearing masks, it's absolutely absurd," he said.

It won't be compulsory for shop workers in England to wear a face covering because "it won't always be right for every setting in a retail environment", according to government minister George Eustice.

However, Mr Eustice says that many workers already wear coverings or are protected by a screen.

He argues that retailers "have been making the right judgements".

The minister for the Cabinet Office was spotted not wearing a mask in a Westminster branch of the lunch chain on Monday, the day after No 10 announced it would be made compulsory to wear one from July 24.

It will still not be mandatory for shop workers to wear masks:

So, another half-hearted effort from the government .....

I agree, we should have been wearing them at the start, they're so uncomfortable , specs steam up, but if they protect us , it's worth it

I keep having to put my glasses on and off again.

Glasses should be over the top of the mask and the nose clip needs to be moulded to the nose so it doesn't leach air upwards. You're meant to pinch the nose clip and then pull the mask downwards. Then you put the glasses on.

The ones that fold vertically are better in that respect. Moulded ones are the most difficult to use with glasses.

What we need now is mask fitters just like you have a bra fitting service in some shops. But of course you can't do it in a socially distanced way. Perhaps we will soon have our own personal robot to do all these things...

Yes, I found that out myself Annie.
Everytime I breathed out, my glasses steamed up but then I found it was because I hadn't closed the wire top close enough.

A tip doing the rounds at The Royal College of Surgeons is to wash your glasses in soapy water, covering the whole lens and either letting them air-dry or gently drying them off with a microfibre cloth.

This leaves a thin surfactant layer on the lens, which should help to prevent the lens from fogging up, although it doesn’t work on all lens types.

You can also try folding a tissue and placing it across the bridge of your nose inside the mask to absorb the air coming up.
