While paying groceries over the counter at a nearby convenience store, I was surprised that a complete stranger unexpectedly asked me how much was the fresh milk I was buying. Of course, I didn’t answer. I thought it would end there. Then he asked how much the chocolate drink, the canned tuna, and the bottled juice were. I’m not stupid enough to answer those questions and act like a salesman. In fact, I don’t even know him. Moreover, doesn’t he know that he might be a distraction? He’s lucky I was in a good mood that time. Anyway, it may sound to you that I am making that incident a big deal but certainly, I believe that this is a matter of social values, norms and ethics.
