No fucker is wearing them anyway. I’m currently on public transport and not a single person under about 20 is bothering, and around a third of those over 20 are not wearing one.
Conversely, I've just got off a bus on which all passengers (aged about around 14 and up) were wearing one. The only exception was a small baby who obviously didn't have to.
Does my anecdata negate yours?
