Gas Pump

I had to visit the neighborhood gas station for a minor fill-up (y'know, the $30.00 kind).

For the past couple of years I have paid at the pump with a credit card rather than actually interact with a human being.

I noticed that the gas pump makes two different kinds of beeps. There is a beep when the gas pump is trying to tell you something, and another kind of beep when it is acknowledging some action taken by the human interacting with it.

For this recording, the first beep you hear is a D5. The gas pump is asking me if I would like a receipt.

My "NO" response is replayed to me in the form of a C6.

Thank you, friendly gas pump!
