Carwash operators can learn by looking at what they have done and observing their success. First, the menu signs are simple and located right in the customer's face with prices that are easy to change. Third, daily specials or features are advertised with few words on large, brightly colored posters and displayed before the menu board. Finally, upgrading is made easy. Every time an order is taken, the cashier repeats it and asks if the customer would like to add anything to the order.
Customers know what to expect through colorful pictures and signs.
The next step in the process is the transaction. Some people don't like to order through a speaker and prefer eye contact. The speaker system does, however, give the customer a chance to reconsider the upsell pitch before the transaction is made. Carwashing is a customer service business and the service order is the first personal contact with the customer. Make it special with a smile and a pleasant, personalized greeting.
