I don't think so, no. Unfortunately a lot of people, when called out on doing something they know themselves is wrong or misguided, go on the offensive "doubling-down" as the Americans call it. I think when you see this kind of behaviour, it's just another sign that you have to be cautious about assuming people are following guidelines. Whenever we go out, we might be around people ostentatiously following the 2 metre rule, but what are they actually doing at home? Are they having visitors, or visiting others and not maintaining social distancing? We can't assume from seeing people's behaviour in one environment that we can be sure about their behaviour in another. We all take a risk every time we go out the front door (or back door) in the current climate. We are all relying on others' decency in not putting those they interact with at risk. We have to stay home as much as we can and minimise the number of times we are unwittingly exposed to risk by thoughtless and selfish behaviour from those we encounter.
