Any wonder the Covid virus isn't contained?
Have a look in the rearview mirror when the little flash goes off. That's the mouth breathers using Snapchat and dropping their masks to do so.
Resting the mask on the chin while chatting to their pals is another favourite.
No mask at all says "I'm high on drink and /or Coke and it's a loada bollocks".
I'm guessing the condoms stay on the thumb when these cretins mate, perpetuating more mouth breathers.
