It stinks when you do such a shop, and then you get so many follow up calls. But I guess there's a part of a secret shopping, sometimes you get some extra baggage afterward but it disappears after a while. It's happened to me, but I try to use it to my advantage in other shops where I can. It works. Think of some unique ideas and try them out yourself. Happy shopping
So, somehow I became a local Google Maps guide so whenever I see a shop that has different hours than are stated or a store that has either closed or one that has opened and isn't yet listed on Maps, I report the changes to Google and they update the information. Unfortunately, I don't notice that happening, especially with hour changes (except during the holidays), so I usually do more picture taking & ratings.
