can Rover clients give a bad review based on a refusal to watch a dog after a meet and greet?

Just wondering if anyone has had experience with this, I recently had a meet and greet with a man (he didn't realize he didn't have to bring his dogs...), and got a rather sketchy vibe from him, and I am wondering if I decline to watch his dogs, if he would be able to write a negative review for me? Can Rover dog owners write reviews just based on a meet and greet? My own dog is very submissive and I am looking for only other submissive dogs so he is comfortable (this is all stated in my profile), and so in the future I am planning on being slightly more selective (he was attacked recently), but am curious if this will effect my ratings?

Thank you for reading!
