What Did Grandpa Do?

I work at the reception desk at a retirement center. We frequently receive calls from confused/sundowning elderly people trying to contact friends or family who live in the facility.

Me: *Answering the phone* “Good morning! This is [Facility] how may I help you?”

There is no answer, only the sound of shuffling and button pressing.

Me: *Louder* “Hello? Hello, this is [Facility]. May I help you?”

There was more button pressing, and then in the background, there was a sudden, scandalized cry of, “GRANDPA, NO!” before the call abruptly disconnected.
