Is there really a need to develop training improve customer service? Why?

Yes

Explanation:

The customer must feel happy, and comfortable in the environment that shopkeeps set up. An unhappy customer is far less likely to purchase in quantity and may be less attracted to products. The experience of shopping must be positive if the manager wishes to succeed.

Examples may be seen in MacDonalds, where the "Happy" meal exists, where bright colours are used and service must be supportive of the customers needs and thoughts.
