I think they did that during the war Barry only they forgot to leave masks in the room. Does seem odd though, I was in a large indoor shopping centre recently masked up of course when a man walked through without one on.It’s too wishy-washy. The rules state that you will wear a face mask unless you are exempt. A valid exemption seems to be that you simply don’t want to wear one. People are free to make up an excuse without it being tested for truthfulness.
My suggestion would be to put all these “disabled” people in a room with gas masks available for use. Then fill the room with noxious / irritant gas and see if they put on a gas mask. Those that do put on a mask are clearly lying when they say they can’t wear them, and those who succumb to the gas are genuine.
Why hasn’t this been thought of before?
Security "invited" him to leave but he would have non of it, more security staff joined in then shoppers got involved pushing & shoving commenced until they got him outside. I do wonder what the hells going on sometimes, the centre has signs on the doors telling you not to enter without a mask so if it causes you aggro then don't go in ... easy.
