On a first visit to a coffee shop I intend to “review,” I don’t announce my visit (if you can call my write-ups reviews). Unless I am specifically invited. If I do get the special treatment, I’ll disclose that. I pay for all of my coffee unless mentioned otherwise. I often will make multiple repeat visits to a place (when it is convenient) and never disclose that I’m doing reviews. Nobody has asked this lately, but I wanted to disclose it. I do enjoy getting free stuff, who wouldn’t, but I work hard to not let it impact my opinion, and the free stuff usually follows dozens of visits. If I don’t have anything nice to say, I’ll often say it with photos.
