Thats how my place was set up, we got COVID secure in a week, reduce usable desk numbers, put up screens, reduce points of contact, change working patterns to minimise contact, let those who can work from home do so, admittedly we have an asynchronous workforce so easier for us than many others.
Not everywhere can do it, but a lot of places can and have. My point was that we are not under lockdown currently, so thats not the biggest factor for struggling bars/cafe's/restaurants/coffee shops/etc. The lockdown is another symptom, its not the disease. Had we never locked down, trains and office would still be empty because people are scared, in many cases, for good reason.
The initial lockdown taught a lot of people and companies that other patterns of work were more viable than they thought. We need to knock the virus on the head, but when we do, we won't be going back to exactly the way things were a year ago.
