DefinitionA service mark (サービスマーク) is a mark attached to intangible services (役務) to show which business provides them.
ExplanationIt is used in businesses such as hotels and barbershops that provide the work itself rather than handing over goods. Typical examples are service names or logos shown on shop signs or staff uniforms.
AnalogyWith nothing to take home, it is a name tag hung at the shop front to show whose service you received.
Memory hookService means work done for others. Remember it from the English word: a mark for what people provide through their own effort.
