So, will the conditions for virus spread be better today with people looking to go shopping, taking buses and trains etc. on a dull rainy day, than people 2m apart on a beach outside in the sunshine?
Absolutely.
However, we've not been to shops yet, have no intention of going today nor any time in the near future. Now, whilst I get these actions (or lack of action) aren't very good for UK PLC, we just don't want to be part of increasing the likelihood of virus spread if we can help it. There's nothing we need from shops, so we're not going to go.
Our old routine on a day like today may well have seen us head to Brighton, mooch a few shops and then grab some food in Yo! or Wagamama. Even if those places were open again, I just can't see we'd be doing what we used to do, and I can't imagine we will for some time.
My concern, based largely on what is happening in many US states, is what will happen once pubs and restaurants open their doors. We'll not be in any rush at all to eat out.
