When Fangfang gave the medicine which the customer wanted, the customer paid and left. Fangfang was a little unhappy though. She had recommended a new type of medicine to him. In the end, the customer only wanted one particular brand and insisted on it no matter what.
No matter how much Fangfang wasted her breath recommending it or used her looks to flatter, the customer was still stubborn. He was very determined! Fangfang had no choice but to give him the medicine he wanted. There was no difference in the effects between the two medicines. However, the price of the new medicine was more expensive. Thus the pharmacy could have gotten more commission.
If you have some ailments and went to the pharmacy to buy commonly used medicines that had been in use for a while, you needed to be more careful if the pharmacy staff enthusiastically recommends new medicines which may come with new packaging and new curative effects to you.
