No one ever delighted a customer by being 'good enough'.
Listen to customers and you will hear them. Look carefully at customers and you will see them. Do both and you will understand them.
Do what's right and you'll never go wrong.
Everything ordinary has the potential to be extraordinary.
Acting after being asked is compliance. Acting without being asked is kindness.
If you want to stay in business, satisfy customers. If you want to excel in business, delight customers.
