Third passenger gets on, notes a majority of non mask wearers, takes mask off. (Can you see where this is going.)
49th passenger gets on - hey, it's Mobyduck! All 48 passengers are without masks, but every single one of them would have continued to wear a mask if everyone else did.
50th passenger gets on - it's someone from Sheffield, wearing a hat of some sort as well as a mask. "Hey, Mick", he says. "Why aren't you wearing your mask?".
