Actually, my first job was an assistant in a pharmacy, in our family pharmacy back home. There was a customer that entered and he needs a special medicine. And there are certain rules that like prevents us from giving certain medicines or special medicines to like normal customers, like he has to bring a doctor's prescription. So he was angry and like started to yell in the pharmacy. And I tried to tell him that there is certain rules I can't, like I may be in trouble if I gave you this medicine. And I started to make him calm down and like explain the situation for him until he finally like I convinced him and he left without any harm to anyone of the pharmacists that were in the pharmacy.
