And they should have adequate backup from "the authorities" to ensure that they are able to enforce. I can well understand the dilemma of some shop assistant faced with a refusenik non-mask-wearer - do they risk a violent confrontation, or just serve the twat and get them out of the shop?This is true. Perhaps the other thing some people are missing is that they're not expecting 100% compliance with this, as with other Covid measures. It's like the rules on face masks. In an ideal world everyone would have to wear a medical-grade mask in any public space, but that's just not going to happen and trying to make it so would probably be counterproductive, and since any face covering is a lot better than none the rules are framed so as to allow people to cover up with pretty much what they like.* Similarly, they're well aware that groups of more than six are going to continue meeting, but probably a lot less and not so much in public places, which will help to drive down transmission. There's a sensible degree of flexibility built into quite a few of the restrictions IMO.
*That's not to say the rules on masks are being enforced adequately: they just aren't. Shops and public transport providers, especially, should be much more aggressive about refusing service to people who won't mask up.
Of course - as was the case with drink-driving - the smart move would have been to be constantly bolstering the public view that masks were an essential part of limiting infection, and support for the measures, so that social pressure became an important part of compliance. The utterly incoherent approach the government has used has pretty much ensured the opposite.
