I’m just hearing the term “wagies” for the first time, and I don’t like it. Workers who deal with obnoxious customers like Anon deserve common courtesy, not a demeaning nickname.
I guess it’s like racism and other forms of bigotry. Creating a reason to look down on others (even when, deep down, you know it’s bullshit) helps you feel less awful about your own pathetic self.
On the assumption you are just wayyy out of the loop rather than trolling, the tv show you'll want to google is severance. It can be pirated wherever you get your shows.
