My Name is Not Boss, Dude, or Chief!

Several people have told me I am too sensitive about this issue but I treat every one I speak with in person, on the phone, via email, Facebook, Linked In, etc. with respect and use their proper name. Why does it seem that candidates, sales people, customer service reps, call center associates, etc. believe it is okay to call people Boss, Dude, Chief and assorted other titles? Quite frankly, I am reluctant to work with candidates who repeatedly demonstrate such behavior. Think about it, how would you feel if a called you about an opportunity and said, "hey Chief, have I got a job for you Dude!"
