Polite young woman said she was "representing Peterson Cat Machinery", who we do a lot of business with, and asked for the owner by name. Still, the number didn't look kosher (RDA Group?) so I googled it while she was on hold and it looked like sales of some kind. I got back on and offered to take a message, but she declined and said she would call back. Very polite, but a nonsense call just the same.
