If people wish to continue to wear masks after next week, that's entirely up to them. But if businesses are to "encourage" their use through endless posters, a barrage of announcements, and maybe a hi-viz wearing employee at the door, then this is where the line between choice & mandate by guilt blurs.
@Watershed mentions the comparison between religious doctrine and mask wearing. For some its just a means to an end, for others the mask has moved from something that might ot might not help to a symbol of safety, and that their absence on others signals instant danger. I see this all the time, from people leaping into roads to avoid passing an unmasked pedestrian through to people exchanging angry glares, comments and even outright confrontation. Masks have become for some not an option but an obligation, and in some eyes a cause of anger when masks are not used.
The government should be advising business to choose if they want to allow masks wearing, not the other way around. We all know what awaits us next week. The announcement in Tesco's blares out "We invite you all to wear you mask for your good, and the safety of all those in our stores.", and dozens of people behind masks turn to those without and glare at them as if they were some murderer or terrorist. One eventually pipes up and confronts someone, voices raise, tempers fray, and eventually someone takes a swing. Rinse and repeat. After all we have been through, more angst and anger is the last thing we need.
I will not be wearing masks next week, I will respect those who do so long as they repsect my decision and don't treat me like some leper.
