From my observations, it's more an age related, as to how seriously the distancing is taken. I've lost count of the number of times, younger couples coming towards us on pavements, don't make any attempt to fall into single file to pass, leaving us to step into the road, on one occasion not being able to do that because the road was too busy so had to enter the private parking space at the front of a house to avoid a couple who continued two abreast holding hands.
Surrey is on our doorstep, we drove down to Haslemere and surrounding countryside on Saturday, passed a lot of pubs with gardens, people were spaced out there. We did have an outside coffee on the high street. Generally everyone was careful to avoid each other. I certainly wouldn't venture up into central London at the moment and from footage on television, demonstrations and drinking out side pubs etc., social distance isn't evident. I also wish face coverings were mandatory in shops.
