People and services that help the public are part of daily life in a city or neighborhood. A service is something people or organizations do for others, such as helping with safety, travel, mail, or repairs. You may hear words like office, staff, worker, and department when people talk about these services. A public service is meant for everyone, often through the city, the state, or the government. People go to these services when they need information, help, or official action.

When people talk about emergencies, they often need the names of the first responders. A police officer helps keep order and responds to crime or danger. A firefighter puts out fires and helps with rescues. An ambulance is the vehicle that takes sick or injured people to the hospital, and an emergency room is the part of the hospital that treats urgent cases. In conversation, people also say paramedic for a medical worker who gives emergency care outside the hospital.

Water and gas are other basic utilities people call about when something is wrong. A repair fixes something that is broken.
