If you can… I would do so.
Individual choices…can still make a difference - no matter when the Government or employers decides to go for stricter measures.
Hopefully people will not crowd in the shop - but you also might try and push for a bit of safety measures (like having less people allowed in at the same time).
Also avoiding visits to relatives (and of course friends) is a very good idea.
Of course, helping one another with shopping, but without going in the house and keeping at a distance as much as possible.
It is weird in the beginning…but I guess it’s worth it.
