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.
A Nerve electrical impulse only travels in one direction. There are several reasons nerve impulses only travel in one direction. The most important is synaptic transport.
In order for a "nerve impulse" to pass from cell to cell, it must cross synaptic junctions. The nerve cells are lined up head to tail all the way down a nerve track, and are not connected, but have tiny gaps between them and the next cell. These tiny gaps are called synapses.
When you get a nerve firing, you have probably heard that it is an electrical impulse that carries the signal. This is true, but it is not electrical in the same way your wall outlet works. This is electrochemical energy. Neurotransmitters are molecules that fit like a lock and key into a specific receptor. The receptor is located on the next cell in the line. When the neurotransmitter hits the receptor on the next cell in line, it signals that cell to begin a firing as well.
This will continue all the way down the length of the nerve track. In a nutshell, a nerve firing results in a chain reaction down the nerve cell's axon, or stemlike section. Sodium (Na+) ions flow in, potassium (K+) ions flow out, and we get an electrochemical gradient flowing down the length of the cell. You can think of it as a line of gunpowder that someone lit, with the flame traveling down the length of it. Common electrical power is more like a hose full of water, and when you put pressure on one end, the water shoots out the other.
Therefore, nerve impulses cannot travel in the opposite direction, because nerve cells only have neurotransmitter storage vesicles going one way, and receptors in one place.
