Sooner or later identification is necessary and being unable to see a face renders this impossible. We have enough problems with people wearing hoodies and scarfs; banks and building societies ban people wearing full face Crash helmets, so how do you know who is under there, with these? If we all walked around wearing face masks, how long before trust really started to break down? Whilst we are a multi-cultural society, there must be some things which we must operate to common standards, so this looks sensible. Otherwise do we all cover our faces when dealing with women in this garb? How comfortable would they then feel?
