It happens across class lines _but_ I find that it's not the same degree. I find that the more used you are to people cleaning up after you the less that you thank them/acknowledge them for doing so. The teenage "I can leave my trash here - they have cleaning staff to clean it up!" mentality seems to be more prevalent the higher income your background is. I say hello to the cleaning staff, security staff, delivery drivers, food service workers, etc at work. I can't get my job done unless they're there, and I am acutely aware that our professional experience and treatment by management is significantly different.
