I have a question for you. Do you have instances where co-workers are openly hostile to each other? I have worked many service industry-type jobs before and never have I encountered the specimens I deal with on the front end of this place (big box national chain).
The rudeness starts with the top manager then goes to two head cashiers and then throughout many of the cashiers. Fortunately, I'm past the point of being bothered by it and now don't really care, but I am curious about your experiences and if this happens everywhere.
I am of the mindset of treating everyone with respect until they piss me off and then I'm cold and indifferent to them, but I am never hostile, especially around customers. Just curious.
