If you are on the front line of customer service, you've heard it a thousand times--"Smile!" What you may not know is the effect of smiling. Smiling is not just about looking inviting to customers. It is also a tool to help influence their attitude to produce a state of agreeability. Customer service is about pleasing the customers, of course, but engaging them in an atmosphere of positivity reduces your stress, minimizes risk of conflict, improves the bottom line, transforms your attitude, and allows you to go home at the end of the day more satisfied with your job. That's a lot of power from a smile.
