One of the greatest ways to ensure that your customers are really satisfied is to be consistent in all aspects of your business. Offer consistently good levels of service, open at the same time consistently, sell the same products consistently, have the same faces behind the counter consistently. Consistency is a powerful tool that all customers like and feel secure with.
Restaurants and cafes that can offer consistently good meals and service are almost guaranteed to succeed. Unfortunately, many offer consistently poor meals and lousy service.
Working towards a level of consistency is harder than it sounds. People, by their very nature, tend to change things around. That is the nature of the universe. For this reason, ,offering a consistent product or service is tough. It's the principle that the fast-food giant McDonald's has been built upon: consistent hamburgers and fries anywhere in the world.
Customers look for consistency in businesses. If you can meet this expectation, you are well and truly on your way to really impressing your customers.
