Which behavior is considered a courteous way to deal with a client
erica [24]

Answer: Several behaviors can be considered as cuts when dealing with a client.

Explanation:

Human beings are social beings, we like to interact with each other, but often these interactions do not always occur in the right way. There are several jobs where people have to have an approach with the client and treat them in the best way, which is part of providing a good service.

Various behaviors are considered as cuts when dealing with a client, one of them is being efficient and friendly. When a client enters the person must show a friendly attitude, which allows the client to express what they need. Efficiency must also be shown at the time of performing the work since a person who is occupying a job is because he is capable of performing the work.

Another behavior that can be considered as cuts when dealing with a client is to listen actively. Many people make the mistake of not actively listening to their customers, which can often cause problems when providing a product or service, or simply listen to the customer's complaints. It is important to make the client feel that he is heard, that what he has to say is important.

Keeping calm in any situation is also a way of being courteous to the client. Each person is different, so not all of them will have the same mood at that time. It is important to remain calm and be professional when dealing with a client. It is not correct to respond inappropriately if the client does so, professionalism must be above all. If a client behaves in a certain way, reporting it might be a good idea, but not reaching the point of using the same tone or way of acting that the client used at the time.
