I found this included in an article, "How to Build Referral Programs", on morebusiness.com, which is a website for entrepreneurs.

They listed a number of steps you can take in your business for generating referrals from your existing customers, but this one below was of practical interest for this site.

"Another way to get referrals is to offer a unique experience that no one else offers. If all other doctors' waiting rooms are boring and filled with old magazines, your waiting room should be a fun place to go with free babysitting and snacks and entertainment and maybe it should look like a café rather than an institutional room."

It's very true when you think about it.  When you walk into your office each morning, are you impressed and proud of your waiting room or is it blah and stale?  If you can create some "Wow!" to your waiting room, it'll get around because when your customers/patients leave, someone is bound to ask, "How'd it go at the ________?"
