//Maybe the Eejits don’t want to catch Covid...//
Maybe they don't (after all, who does?). But they will not be protected from it by wearing a flimsy, ill-fitting mask which they stuff into their pocket and drag out again as they go about their daily business. In fact a well fitting flimsy mask, even if worn and treated properly, will not provide that protection.
Instead they should treat themselves to an FFP3 facemask and, provided it is worn and treated correctly, that will give them 99% protection against SARS-Cov-2 as well as all the other airborne viruses which are around and which present similar risks. They should be prepared to do that forever and in all environments, mind you, because as soon as they venture out without their mask they run the risk of contracting the virus. If they are not going to carry on the habit indefinitely they may as well not bother because, come the day, they will almost certainly be exposed to Covid.
