The customer is always right. It's a staple of many customer service-focused industries, and retail is no exception. Retail Customer Experience recently pointed out a plethora of other do's and don'ts to ensure customer satisfaction and loyalty isn't compromised by the wrong action or statement.
For example, when it comes to communication, there are some phrases to watch out for. Never reply to a customer question with "No," unless an alternative is prepared, never deny authorization to provide a discount and don't say "No problem," as it sounds condescending. It should be replaced with "You're welcome."
Furthermore, two women should never be referred to as "you guys" (for obvious reasons), and the answer to any question should never be "I don't know" - ensure the customer that someone who can answer the question is being located.
Lastly, in terms of attitude, all problems should be left at the door, never ask to go home early, don't blame the traffic on being late and don't complain about the Christmas music, since it's playing for the customers, not the employees.
Speaking of the holidays, the National Retail Federation reported spending per customer on Black Friday increased 9.1 percent over last year according to Minuteman News Center - a good indicator for future revenue growth this season.
