Insincerity

I get really annoyed when people drip insincerity. Just lately I have had several phone calls from someone about a business matter. They always ask me how I am and say, "Oh bless you" after almost every sentence. Of course they don't give a monkey's about me, and why should they, we have never met! My husband tells me I should tell them to stop that silly nonsense, and tell them to cut to the chase, and so help me I probably will, it is beginning to bug me so much!
