I appreciate slimy salesfolk being obvious. I’m not a fan of people using my name at all, first or last. Just talk to me.
A while back I decided to contribute to training for guide dogs. They set it up like World Vision used to (maybe still does) and send you updates of “your” dog’s progress. So I decided to pay it each month in my granddaughter’s name so that she would receive the messages and videos as I thought that she would enjoy them. When I went to do it, I realized that I had no idea what my granddaughters last name is - her mother’s family name or my son’s. So I had to ask.
