I realise I'm late to the party but damn. I hear the old plea EVERY SINGLE DAY of my working life (sometimes more than once!) of "I'm really sorry, please don't ban me or tell my parents, I won't do it again, I promise!"
To which the usual reply is: "Um, this is the forth time we've caught you, you little shoplifting scumbag. Oh, and you're banned. And I'll be calling your parents in just a minute so they can come see you get arrested, because I'm also calling the police."
So, in other words, keep the **** head banned.
If I ever see him anywhere trying to do anything untoward I will have no problem flooring him and making sure it hurts.
