How do you make your customer's feel? Do they feel appreciated and valued? Do they feel that you respect their time? Relationships are the cornerstone of any successful business. Customer's have choices about where to invest their money.
Where do you invest your money? Most likely it is with businesses that you feel value your business, with people that you like and even more importantly with people that you feel like and respect you.
Make your customer experience one that leaves a lasting memory. People do not always remember what we say or even what we do - but they ALWAYS remember how you make them feel.
