服务意识
In my opinion,as a businessman,one should always be aware of the benifits of the customers,such as the quality of the goods,service attitude,as well as the prices which can also be sensitive to the customers.What's more,having sold the goods,the most important thing for a businessman is after-sales service.How to deal with this probem well isn't an easy thing.However,those who can do it well will certainly put themselves in an invincible position in the world of business.
