Well yeah but why not maximize efficacity? I mean at this rate just taking care not to sneeze directly in people's eyeballs is better than not doing it, but that doesn't mean it's sufficient. And putting a mask on correctly is not hard or time consuming.
Good analogy @purplepumpkin and yes please it is not such an effort. People tell me directly "oh is impossible to breat with these". I'm an essential worker, they tell me this while I'm working, when they have been home all day just wear it when they have to go out. I'm wearing all day. I'm alive. You'll be fine. Just wear it. I have been in contact with people with the virus. I have been spared so I'm wearing. (Not talking to you but in general to those people I just get really annoyed lol)
I imagine it has something to do with not being convinced that the specific way you wear the mask is line between sufficiency and insufficiency, coupled with wearing the mask properly being annoying to them.
Cause I don't want the virus
