An update here from the Czech Republic, "mandatory" certainly means that you can take your face mask off when talking to a person, who is hard of hearing, just keep your distance. All the TV newscasters wear face masks, the sign language ones have transparent shields. Face masks have moved on a bit from the first batches of home-made ones. Now women have ones to match their outfits, businessmen have sombre grey or navy to maych their suits, children have cartoon chatacters, the police and army have their own. I made some in the first instance, but I'm not very good at this, so I bought ten from some ladies from a bridal salon, who would otherwise be out of a job, they (the masks) are luxurious, made of very fine cotton, double-sided with elastic round the ears. We are told we'll be wearing them until July, maybe forever.
