Nice People......Apparently There Aren't Many in the World of Customer Service

I just got off the phone with a customer service rep from my piano rental company. He said "thank you for being such a nice person." Wow. I was just being a normal person, but apparently that is nicer than some? I didn't know how to respond to that, so I went with the classic "no problem." Hahahahaha. How would you respond? :)
