I don't like sales pitches disguised as social get-togethers. Maybe it's not exactly the same thing, but an old work colleague once said he'd like to come over to my house and play catch-up. I'd been over to his house a month or two earlier to have dinner with him and his wife, so it wasn't completely out of the blue. As we were sitting out on the back deck, he started talking about options for purchasing my electricity, and it suddenly occurred to me he wasn't interested in making a social connection at all; he wanted me to sign up with him for power distribution. It didn't happen, as I was already fairly content with the service I was getting from the local power company, and not too happy about the fact that he had been dishonest about wanting to develop a friendship beyond work.
I guess I just don't like dishonesty.
