Who do you represent?
When a customer or client walks in or calls on the phone, answer with a cheerful and professional voice. This should be according to the general population, not what you feel is right. You are not representing yourself, you are representing a company that depends on customers and clients for their income and your paycheck. You should have a clean and appealing appearance. Dress clean, dress professional according to company standards, and make the customer your number priority. Do not talk to friends or other employee when a customer is in the office, unless it is business that cannot wait for five minutes.
