Am I being overkill?

Okay guys I have some family members that will not cover there mouths when they cough or sneeze this includes enclosed spaces like cars😌 I get mad when they do this and ask them to pls cover there mouths but sometimes I feel like maybe I’m a little over kill lol
What do you guys think? Are you guys bothered by this or would you be?
