I'm wondering what has caused the general public to remove the politeness filter (for lack of a better term) in dealing with service workers. I don't remember this being such a commonplace occurrence years ago.
Maybe it's the anonymity of yelling into a phone or knowing that a low-paid help desk person can't yell back (the customer is always right)? I'd actually like to see a few companies start blacklisting the most outrageous offenders and put their employees' mental health first.
