I recently had a call from a client who owns a service station. We have been cleaning his customer restroom for quite some time and he wanted us to also add his shop restroom to our cleaning schedule. What he said about his present service was:

We get a lot of compliments on our restrooms;
and that’s rare for a service station.

Exceeding the expectations of your customers produces goodwill, positive business image, and return customers. Feedback like this confirms my supposition that the value our customers receive as a result of our services is far greater that the cost of our services.
