Customers satisfaction, if at all you want your business to succeed, is very important. Fail to deliver [be it quality products, services or whatever it is your customers need] and you'll be out of business before long. Exceed your customers expectations and you'll have built an army that will help you with marketing. They'll tell their friends about your business, friends will refer more friends and your business will keep growing . . . Strive always to satisfy your customer's needs and you'll reap some rewards.
