Rouge store manger with no customer service skill

The store manager Lifuno felt that my friends and i were a bit roudy and he expresses this in a very rude manner. Not only that,he hits my partner 3 times on his back moving him from the counter. I apologise for the behaviour but point out my dissatisfaction at his approach and him putting a hand on my partner. He continues to be rude and and asks me if im his \spokesperson\" and persues a very heated and loud argument in front of other customers. Im disgusted at this behaviour,his lack of respect considering there was no prior request or 'warning'
