It appears that some will only take notice and start acting responsibly when they think their nuclear family may be affected.
I'm in Tier 4 also and over the months I've seen a lot of people being careful and doing their bit but also some of these more unruly types.
In this example, surely the parent who was able to wear a mask should have gone into the shop and the other parent (who presumably was exempt) should have remained outside with the children (and scooters) so as not to put everyone at risk? But no, it seems it was too much of a bother for them
I sometimes wonder what it would take for some to start taking things seriously so that we can get out of this mess
