I have a pretty strong background in Sociology, so you will forgive me if I pretty much kick the interpersonal elements of this debate to the curb. This is not to say that these elements are not important, rather that I think that the systemic or societal element of this issue is being tragically underplayed.
I am reminded in a lot of ways of the Stanford Prison Experiment. This was a pretty famous study where in several run of the mill folks were given the rolls of “Prisoner” and “Guard”. The study itself has a lot of nuances, but the gestalt seems to be that once given these rolls, the students began to act like guards and prisoners do in real life, suggesting that the way that people behave is very strongly influenced by power dynamics or what is expected of them.
So, msmith537, when you say things like:
I would say that you are contributing to the problem. Again, I am not talking about the interpersonal level. I am talking about the institution of customer service. Your statements, and indeed your whole post, seem to show a level of contempt for that occupation. I would argue that attitudes like this basically feed the problem.
It is clear to me that in general the folks that work in professions other than the service sector, at best, have feelings of superiority to the service sector workers and at worst some elements of contempt. What I think would be an interesting matter to think about is which came first; societies contempt for the service sector, or the etiquette and decorum of the service sector beginning to erode.
