$4.$ Mary recently brought her child to the Express Clinic at their Big Market Basket Food Store. This convenience clinic is staffed by a nurse practitioner from $8$:$00$ am until the store closes at $9$ pm $7$ days a week. The nurse practitioner did an exam and prescribed a prescription for an inner ear infection. Mary had it filled in the pharmacy and returned home. Shortly afterward, she started to have second thoughts. $$Should I have just waited and taken my daughter to the pediatrician?$$ she wondered. Two days later, she got a newsletter from the Express Clinic. On the cover page she saw a story headline that said, $$In a recent survey, $97\%$ of the mothers we surveyed were extremely satisfied with the care they received for their children at Express Clinic$.$ What strategy was being implemented by Express Clinic? What was the organization trying to counter?
