I received an unsolicited call from Southern Water.  They were offering a free water test, to which I agreed.  ( googled the company's name while I was on the phone to confirm they were legitimate.  The company name showed on my caller ID.) I was asked a number of personal questions as the appointment was set up, none of which had relevancy to the quality of my drinking water.  I didn't answer them.

A few minutes before the appointment, I received a call from a man to confirm the appointment.  I asked some questions about the company, let him know that I didn't understand why their sales personal asked me questions about my profession.  He told me that I was a "[***], at which point I hung up.  It was disconcerting to say the least.
