(a) The proprietor or other person, firm, limited liability company, corporation, or other entity that owns, leases, manages, operates, or otherwise controls the use of a public place, public transportation, place of employment, or public meeting shall make reasonable efforts to prevent smoking in the public place, public transportation, place of employment, or public meeting by:
(1) posting appropriate signs or by any other means which may be appropriate; and
(2) asking any person who smokes in an area where smoking is prohibited to refrain from smoking and, if the person does not refrain from smoking after being asked to do so, asking the person to leave. If the person refuses to leave, the proprietor, person, or entity in charge shall handle the situation consistent with lawful methods for handling other persons acting in a disorderly manner or as a trespasser.
(b) The proprietor or other person or entity in charge of a public place, public meeting, public transportation, or place of employment must not provide smoking equipment, including ashtrays or matches, in areas where smoking is prohibited. Nothing in this section prohibits the proprietor or other person or entity in charge from taking more stringent measures than those under sections 144.414 to 144.417 to protect individuals from secondhand smoke. The proprietor or other person or entity in charge of a restaurant or bar may not serve an individual who is in violation of sections 144.411 to 144.417.
