Here's a great post from Seth Godin...
The facilities at DisneyWorld are clean. It's not a profit center, of course. They don't make them clean because they're going to charge you to use them. They make them clean because if they didn't, you'd have a reason not to come.
It turns out that just about everything we do involves cleaning the bathrooms. Creating an environment where care and trust are expressed. If you take a lot of time to ask, "how will this pay off," you're probably asking the wrong question. When you are trusted because you care, it's quite likely the revenue will take care of itself.
