Given hardware stores are considered essential my guess is that we will see the masses heading for B&Q to stock up on items for "home projects" they can do during lockdown.
Completely missing the point that the reason they can remain open is to provide supplies to key workers like plumbers to fix leaks that unless fixed would prevent people staying in their home.
I've also got a feeling that we will see people having daily "essential" trips to the supermarket to get out and about.
I still don't think some people are taking this seriously.....
