Your perspective is a generous one. I believe every individual, provider, client, or otherwise is fully aware whether or not he/she is being courteous/respectful/civil. If you know you have been courteous, respectful, and civil towards a provider, I do not believe your behavior should be subject to the provider's judgement. There are individuals throughout society who are arrogant, belligerent, or otherwise antisocial personalities, not only certain providers or certain clients.
