The only way to get the word out is to create memorable situations. Excellent service is not what you believe it to be, it's what your customer perceives it to be. And tells others. Here's what happens if you do. It builds goodwill.
Consistent service creates and builds reputation.
It builds customer loyalty. People will look forward to the next time they do business with you. It creates memorable experiences that will be retold time after time. It makes your customers sales people for your business. And they are a thousand times more effective than any employed salesperson on your team.
