They're, for example, the local Tesco queue 'managers' who are actually doing this ✋ in people's faces, well within 2m of them, eyes ablazing, missionary zeal within their hearts- who are using zero common sense, when everyone is already doing the best they can in a Tesco Local, to stay apart.
You invaded my space (and that of the 'one out' I was about to replace by being 'one in') in dashing out 🤚 and stopping me entering your store because I stepped forward to wipe the handles of my basket. A good 2m from anyone, except you. As invited to do so, by your big sign.
You stood in 4 people's space. Me, you, the couple exiting the shop.
Use your intelligence. Like stand outside the store door, like your colleague suggested to you, under a balcony, on a beautiful day. And like the usual security guard manages.
We're all under pressure. We're all stressed. And in classic MN fashion, I PPE up close to actual Covid patients, every day.
So don't be a dick, Tesco assistant.
