GOODS VS. SERVICES

[1.] Are there any purchases that are purely goods? Are there any purchases that are purely services? Explain.

        For example in a grocery store, you pick your own things you need for your house, yourself, food, car, whatever. You push your own cart and deliver it to the cashier and the cashier punches in your purchases. That's purely goods. Pure tangible products. While purely services are intangible services that you cannot see, taste, or whatever. An example of this is Teacher and Student, the teacher teaches the students about stuff and the lessons she taught is stock right in the students knowledge. So it is purely services.
