This is one of the only places in the world that gives me anxiety to enter. I cringe because customer service means so much to me. (Delivering it- receiving is important too, but if any of my employees treated my guests like these folks do, I would fire them...immediately.
If you are so unhappy with this job that you can insult an elderly woman who is hard of hearing, perhaps you should consider a new position.
There is one man here that does not fit this bill- I do not know his name, but maybe he's moved on to greener pastures. Good for him.
