[dripton]

Some -15 point OPHs, keeping in mind that spitting on the floor is only -10:

* Spitting in other people's faces, or food.

* Blowing carcinogenic smoke in other people's faces. (Though in a society where this is common, it might only be -10.)

* Constantly trying to sell people stuff, even after they've said they're not interested. (If you can take no for an answer, then it's only -10. Unless the stuff is highly illegal and just hearing the sales pitch can get them in trouble.)

* Trying to convert everyone you meet to your massively unpopular religion or political party or Delusion. (If it's mainstream, probably only -10.)

* Habits that endanger others' lives, like smoking around open flame, or pointing your loaded weapon at people for emphasis while speaking, or playing with your mobile phone while driving.
