Haven't encountered any of that, but I can say that my wife, who works in the pharmacy, is required, upon pain of termination, to wear a facemask AND a plastic face shield for 11-14 hours with no breaks (labor laws don't apply to "professionals"). Some busybody-bullies complained when one of the pharmacists in another store lifted the corner of their mask to insert a straw to drink so they wouldn't pass out from dehydration. Management said to go to the back bays where the customers can't see you and sit on the floor to drink/eat. A) the floors are filthy generally because everyone is too overworked to clean them, and b) you then get to handle that nasty KN-95 mask and faceshield and not be able to clean your hands prior to eat/drinking. I told my wife to take an extended bathroom visit and eat something in the stall - she is lucky to get to the bathroom once or twice in an 11 hour shift, so she best make the most of it.
