My family went to a furniture shop last week. We wanted to buy our son's single bed. There're a few salesmen but this guy came to greet us first. He's very friendly. And always smiled. I told him that I wanted to buy a single bed for my son. Straight away, he showed me the best single bed. I looked at my husband, he just shrugged. I looked at my son, he smiled widely. Ok he loves the bed. Settled.

Before leaving the shop, we saw another salesman who was still asking his customer. Asking whether she wanted to buy it or not. Then he looked at me and looked at his customer again. He's not satisfied. 

Sighhh. All depend on their luck. May be, the salesman will get a customer who really wants to buy something. If he is unlucky, he will get a customer who just wants to look around. But the most important one is whether the customer wants to buy or not, the salesman must treat the customer nicely and patiently. You don't know your luck.
