New to Rover- First client without meet and greet for a few hours, should I invite in/walk?

I accepted my first client (Technically second, but that is an extended stay that starts this weekend, we had a meet and greet yesterday that went well) that was a last minute daycare stay for same day, today. The dog is 9 years old and will be staying for about 5 hours while the owner goes out for dinner. Since it is the same day I did not ask for a meet and greet and neither did the owner. Am I expected to walk the dog during this stay even if it's short? Should I invite the owner in to look around as if it were a meet and greet or should I just take the dog at the door? Thank you.
