Striving for impeccability is a hidden goal that produces massive results! How you run your business and how you interact with customers is very much like tossing a pebble in a quiet lake - the ripples reach farther than the eye can detect.
Most obviously, Word of Mouth is effective advertising. If a customer visits your business and is greeted with an attractive display that is fresh and cared-for, that sends a message that your store-front is concerned with presenting the best products in a favorable manner. When the customer is greeted timely and enthusiastically, the message is that this business wants to be involved with its customers.
