Given the microscopic size of the virus, I'm not sure how effective a hatch is at blocking it. I think the hatch/perspex screen just makes us feel more secure.
Well farts can make it through underwear and denim so I'm not convinced that a mask is doing much against Covid19.
Masks are to make other people feel safe.Yeah, when you have some surgical masks allowing [broken link removed] of virions through, I wouldn't put much faith in the DIY ones I'm seeing about, though the COVID-19 virion is larger than that of MS2 at 60-140nm Vs 10-80nm.

True. Perhaps the should legislate for the carrying of holy medals....
Yea, kind of. Your elbow probably does a better job. I wouldn't fancy standing in front of someone who was sneezing or coughing while they were wearing a mask made out of an old shirt or whatever if they didn't cover their mouth with their elbow as well. I'd be equally unimpressed if they were wearing a 70 cent disposable mask.Is the point of masks not to prevent spread via large droplets from sneezing/coughing?

No, FFP3 masks usually have an exhalation value and they are the worst kind to wear as they do not filter exhaled air but do project it further than normal breathing. They are designed specifically for filtering dust and dirt out of inhaled air while offering minimal resistance to exhaled air.I presume universal wearing of FFP3 type masks would make a huge difference but isn't a runner from an economic/resource perspective anywhere.
Yep, my local chipper has a big drawer, like a pot drawer in a kitchen, in their front door. You order via an intercom and they give you your order through the drawer. Contactless payments through the glass. No customers enter the shop.quite a few business have installed a 'hatch' at the main entrance, really helpful
