"A teacher said "you missed a spot" to me once. My response was,"I didn't realize we hired a new supervisor." They now avoid eye contact with me."

Someone thinks they are in the right in this and I want to see what ya'll have to say. I think people clumsily and ineptly try to engage in banter with custodians and what they say gets twisted by someone (the custodian) who is highly defensive so they react with hostility and defensiveness.

Thoughts?
