Learn Manners

I receive a lot of solicitor calls at work. I try to never be nasty because the callers are only people trying to make a living. I wish they would have the same respect for me. The two calls I got yesterday ended the same way. They asked if I used their product and I said, "I am sorry, we do not use that product". I said it in the nicest way. As soon as I said the first 4 words, the phone was slammed down. Who trains these people?
