You act like a child you get treated like a child.
Here is the brief story of the encounter, according to the YouTube uploader:
Guy wanted to sell something to us, that’s what are shop does and he didn’t have all the components so he was asked to just get them and bring them back and he didn’t like that obviously. The guy ends up calling the police and the cops see the video and say, “You asked him to leave and he wouldn’t? I see no problem here.” And that was that.
Major props to the cops for taking the situation in stride and not hold the shop owners responsible for their necessary actions. Moral of the story: Don’t be a d*ck. Actually, that’s the moral of any story.
