I recently visited a cafe in the UK which serves lunches and snacks and it was not on TripAdvisor. So, as in the past with other establishments I have found weren't listed, I submitted a listing request. I have received a reply saying that the cafe "does not meet our submission guidelines" and refers me to the guidelines on the TA web site.
Why on earth should this cafe not meet the submission guidelines? I have read them in total and can see no sensible reason. The TA e-mail doesn't say how I can query their decision.
