Not sure if this a modern N95 plague beak. Maybe. These masks didn’t offer much protection against bubonic infected fleas back in the dark ages, but they looked pretty cool and gave doctors who wore them an air of scary.
The beak is for perfume. If the air smells good, it can’t be bad. (This would be good for podiatrists.)
I suppose you could store other things in there, too. Maybe a little water, some snacks, your cell phone. It offers a sense of privacy, too. No one knows what’s going on in there.
