Yes, that's a common experience. If you ask any store employee a question, and they don't know the answer, they'll think up one for you.
It's a service they provide free of charge so that their customers don't have to think up an answer themselves.
I kinda feel embarrassed offering up this information on involute gear teeth, and then finding out I was wrong, but I know that no one in here believes that I had anything but the best of intentions.
