//No one is doing that though. People are milling around all over the place.//
Of course they are! That’s what people do in pubs. So you either accept that or keep them closed (and destroy an industry that employs over half a million people).
//I think we should have done this in shops months ago.//
Why?
//No, I mean when it becomes compulsory Bobbi - I never wear one, feel claustrophobic about it all!//
Then you won’t have to. You will have a “reasonable excuse”:
=========
For the purposes of regulation 3(1), the circumstances in which a person (“P”) has a reasonable excuse include those where—
(a) P cannot put on, wear or remove a face covering—
(i) because of any physical or mental illness or impairment, or disability (within the meaning of section 6 of the Equality Act 2010(1)), or
(ii) without severe distress;
//I dare say that, if it does become compulsory, those that are not wearing them will be refused entry.//
Possibly. Unless they have a “reasonable excuse”. See the legislation for public transport here:

If the guidance for shops follows that for public transport, shoppers will not be required to provide evidence of their reasonable excuse.
