It is a deadlock between a rowdy customer who acts like he owns the world and a security guard who thinks he is in the SWAT team. The customer would make a scene in the store and the guard would come not just to pacify but to the point of threatening the complaining customer. I had witnessed that scene before in a classy boutique where a matron who looks wealthy was complaining with a loud voice and even using expletives in her spiels. The cashier was humiliated such that she couldn't put up a defense. Thanks to the security guard who almost collared the customer and held her arm as if to drag her away. I shook my head and imagined what would happen next. For sure, the guard would be terminated.
