So, even if you would have proof ... this is a law student in Germany. Even if you might not understand a single word of him show casing bringing back a jacket with a fucked up zipper, hear the tone.
That is normal.
They are all like that.
Except you scare them, or are an Authority.
I am not sure if he suffers from a hidden Narcissistic personal disorder that prohibits him from telling the sales guy, who is no fucking judge at all, that he likes the jacket, but can't wear it anymore by the zipper being broken just a few weeks after purchase even so he did not use any force and instead tries to get a jury going about constitutional rights suing the manufacturer, logistic chain and franchise chain for about murder or at least sounds like, but I am done dealing with that.
