One more thing I will say on these measures is that a month ago I may have thought these were enough.
That however was before iv seen all the steps employers have had to take to remain open during the last month. Retailers limiting 10 customers at a time, one way systems in stores, markings on floors and protective screens around the checkout areas for employees for example. That has set my expectations on social distancing.
So as I say a month ago these suggested measures may have been my expectation, but my opinion has moved on and I suspect I'm not the only one.
