Client that bad mouth prior dog walker? No pics or updates?!?

I just met with a "business" type of a client. He is obviously successful but very busy.

Anyhow, it was our meet & greet and he tells me that his current dog walker is horrible and she doesn't show up and that his dog pees everywhere because she doesn't come in. I was very confused as to why a dog sitter won't show up but shows up on some days. Then, his son came in and he said "I am trying to get rid of the old dog walker."

I asked him if he wants texts & pic updates and he says no. So, unless he has cameras, how would he know I am there?

I told him the dog peeing might be due to marking instead of not being taken outside. I also let him know that I am not going to be responsible for the dog peeing inside because I will be here when I am scheduled.

Also, after I told him that he can't blame me for the peeing, he said I could lock his big dog in his crate. I was told he likes his crate but I feel bad about locking the dog into a crate when he isn't used to that. Also, the client seems very cool about everything - come in whenever but come in - do whatever - walk whatever....

Anyhow, what do you guys think? I am fairly new on Rover and only had very nice & polite clients who all love my updates & pics!
