@Janae40 I can't say this for sure as there is no proof, and is only my opinion/ hypothesis based on what I experienced, however you may have been being tested. This happened to me several weeks ago where I had 8 inquiries, over a week's time and not one of them ever booked and they were all on the same subject. If the questions about your accommodation had to do with anything that could be considered discriminatory, it was likely a test to see how you would respond. I have never had 8 inquiries in the same week, ever, where not one person booked.
