If I get a rude or disrespectful buyer, I generally don't leave a review. I would hate to leave a dishonest 5 star review only to then find out they gave me a 1 star, and I would also hate to leave a 1 star only to find out that they put personal feelings aside and gave me a 5 star. So I just play it safe and don't leave a review. As far as I know, if you have a respectable amount of 5 star reviews that outshines a handful of low reviews you should be okay.
