Negative comment about being handicapped
Several weeks ago, my wife and I had an overnight guest who was extremely negative (even in her online communication with us before her arrival).
I was in a near-fatal car accident two years ago, and I mostly use a wheelchair to move about in my house.
After her departure, this guest wrote among her negative comments in her Booking,com review that she felt uncomfortable speaking with me while in my wheelchair.
I found her guest review comment very inappropriate and offensive. After submitting my protest of her review, Booking,com would not delete her comment that can be read online by everyone.
