Never heard of the word, so thank goodness there was an explanation, but I still do not really know how to apply it properly.
Perhaps this is a ready insight to things before you enter the supermarket. Apart from being counted as there is a limited amount of people allowed, there is this table. On it are two bottles of something disinfecting, probably alcoholic and it is voluntary if you use it or not. Just spray it on your hands and it dries immediately but you are ready to pick your goods, fill up your trolley and pay at the cash desk when leaving. Of course keeping a 2 meter distance from everyone.
What a life we are leading, who would have thought it possible. And so I leave the supermarket after paying with my plastic card, which is preferred against using real money. The final act is to once again disinfect your hands, you never know where those hairy peas are hovering. Now that is my perspicatial act of the day.
