Yes, it is absolutely right.

You should have a pleasant personality in order to impress your customer. Make sure that you talk to them with a smile on your face. It will create a friendly atmosphere between you and your client. Your one smile can make them feel comfortable.

Having patience is another important aspect of a sales job. You meet customers with different attitude each day. Attend to their queries patiently. Do not express any sort of dissatisfaction. Always remember, having patience will give good results at the end.
