If customers say you're just 'all right', you've not done enough, you've failed to delight.
When you see the need, take the action.
If you only give back what you get from other people, you're not giving as much as you can.
No one ever delighted a customer by being 'good enough'.
Words not kept break more than a promise.
Always do what you can do instead of worrying about what you can't.
