Differentiate between voluntary and involuntary services with examples

What will be an ideal response?

Voluntary services are services that we actively seek out and employ of our own accord. Generally, we research a voluntary service, such as a gas station, a restaurant, or a hotel, and have certain expectations when we engage its services.
The quintessential example of an involuntary service is a prison. Other involuntary services include hospitals, the IRS, the police department, the fire department, and other services that you do not choose. If you have the chance to engage this type of service at some point, you likely will have vague expectations about the experience.
