1. Snorting
    Like the intentional, deep, meaty kind. I don't care if you have a cold, it's a disgusting sound. Blow your nose or take it to the bathroom.
  2. Fighting about sports at the bar
    You're at a 10, we need you at a 2, sir.
  3. Free range sneeze
    Into the hand or elbow, people.
  4. Yell at airline staff
    We're all in this together, bro.
  5. Let your children run around, unattended
    Seriously, if they fall or hit their head I'm gonna feel like it happened on my watch.
