Final answer:
The statement in question is false. In the context of emergency services, it is the line personnel (e.g., EMTs, firefighters) who deliver services directly to the public, not the staff personnel who typically have non-operational roles.
Step-by-step explanation:
Staff personnel deliver emergency services :
The statement 'Staff personnel deliver emergency services directly to external customers' is false. Staff personnel normally refer to personnel who work in non-operational capacities, often providing support services rather than directly engaging with emergency services. However, in the context of emergency services like fire departments, it's the line personnel—the firefighters, EMTs, and paramedics—who deliver emergency services directly to people in need.
Emergency medical services, fire departments, and police departments are funded by the government through tax revenues. These essential services are generally available to the public without additional charges at the point of service.
