It's not hard to see the allure of emergency care clinics - they're open at night and on weekends, you can walk in without an appointment, and in some areas of New York City they're becoming almost too ubiquitous than Starbucks. While critics say emergency care patients don't enjoy the quality of care that comes with a long-term doctor-patient relationship, these walk-in centers have set a new precedent of convenience and service for clients. Such as the city's public health system and other service providers. Try to fight back.
