What if the request has false information?
Had a request to sit for 4 dogs, great. At the meet and greet turned out there were 4 dogs and 13 cats? Of course I said no and my score was lowered. Also, had a request to sit for someone who might get a dog in future, again nothing positive or now, what did that do to my score? Obviously it makes it go down!
It's completely rotten but it's true. Your score can be adversely affected by things that are completely out of your control.
