An advertisement coupon placed in a mass mailer, which does not state "this is an advertisement" on the outside of the envelope violates rule 7.2. A lawyer may rent a table or sponsor a booth at a business exposition and not violate rule 7.3, as long as the lawyer does not approach, accost, or importune members of the public in the area of the table or the booth.
A lawyer must not use any deceptive tactics to influence the public's decision to visit or. Not visit the table or the booth. The decision to make contact must always be made by the public, not by the lawyer.
