Masks catch the moisture in your breath. It's like covering your mouth when you sneeze.
Imagine someone walks in a room where you are eating, sits in the seat next to you and starts sneezing without covering their mouth.
"Excuse me" you say, "could you cover your mouth? I'm eating here."
"Sorry," they say "I prefer a risk-filled existence over a safe, constrained one."
Kinda missing the point there, friend.
