Cloak of civility? This boggles my mind.

I asked a question. The question was valid and presented simply and without derogatory language. The seller responded with something of a quip. This would seem to be made evident by the fact that the caps obviously "make a difference" to me, or else I would not have asked. I responded straightforwardly, without derogatory language, and I based my comments upon my knowledge and experience as both a camera user and collector. He responded with two hostile messages. How his remarks could be construed as being something other than offensive is beyond my comprehension.

I am puzzled by sellers (everywhere) more and more these days. It seems that some of them think that answering simple questions or performing routine activities that arise in the course of business is just too much trouble.
