A few weeks ago I had a crazy moment with Locale Guides. We have two hair salons in our town and both use almost the same name. So I added the opening times to one of them as it was not in Google Maps. Then the other owner called me and got totally crazy about it. He said he is his big competition and he now is scared that he is losing customers so he decide to call the Google Maps support and he found my contacts 
He was mostly crying on the phone and asked me to change it so badly and I get free hair cuts for ever (if that works for a company like Google at all…). I told him that I can add his opening times too and a photo of the store and I also do not want to get anything in return, I also explained him that I do NOT work for Google or so and he got totally confused why one is doing that at all.
Finally I changed it for him and he called me two times after to thank me so much…
That was a really strange and kinda cute and funny experience for me.
