It takes some courage to open yourself up to anonymous feedback from customers -- some of which may be unfair criticism from someone just having a bad day -- but the rewards far outweigh the risks. It shows that you're committed to providing a great experience and that you value and respect your customers' opinions. You could even go a step further and post some comment cards -- with your response -- on a message board of sorts. I saw this at my company's cafe once and it helped me feel like they were really listening and acting on suggestions.
