To have a "No Smoking" rule or any other rule for that matter you need to have someone that is willing to enforce it... No one wants to tell the locals or anyone else that smoking is forbidden - in case they get shouted at. You need to have someone that can deal with the back fire in such cases. A trained person who can deal with angry and rude people who become defensive and arrogant when told they cannot do something.

Same thing with seatbelts. The law is there but do you seee every single person in every car all buckled up.. nope.. and the worst thing is sometimes they are in the car right next to a police car !!!
