If it's going to be compulsory for people to wear a facemask whenever they go into a shop, I wonder if the same conditions will be imposed on the employers and employees of such premises?  Over the past week I've seen a sudden increase in the rise of people wearing facemasks since the lockdown restrictions were eased, yet I still haven't seen a single person working in any of the shops or supermarkets I've been to - whether it be shelf stackers, cashiers, Customer Service staff, etc - wearing a facemask!  Is there something in the small print somewhere that states that the employers and employees of shops are exempt from the rule?  They could just as easily spread Covid19 to the customers who are going into the shops if they've come into contact with the virus but are not yet exhibiting any visible or audible symptoms of the disease, so surely they ought to be wearing facemasks as well?
