Last year for work, I attended a 'dealing with customer aggression' workshop run by a police negotiator. The main thing I remember from it is that "prior history" is cop-speak for "dude's a fuckwit". :)
Not at all. It was just an account I hadn't used for a while and had forgotten the password to. I was trying to sign up for premium so I could listen to albums on the Android app.
I have no idea what they're talking about, but I do love a happy ending.
