Man and his son were in the park driving around two remote-control cars. A big dog was in the park off-lead, which is allowed at that time in the morning.
As they cross paths one remote-control car goes near the dog. Dog owner calls the dog over and tells the man and the son that the dog will pick up the car, run off and chew it if it comes too near him.
Man says "okay" and they move on.
Later, they cross paths again on a narrow path.
The dog owner calls her dog close as the man and his son get closer. The man/son keep their remote-control cars going as they pass so the car comes close to the dog.
The dog goes nuts, picks up the car and runs with it.
The dog owner calmly walks after her dog. The man starts yelling at the dog owner to get the car back. The son goes chasing the dog, which the dog completely loves and which gets the dog really excited meaning it runs further and throws the car around like a ragdoll.
After several minutes, the owner catches up with the dog. The toy car is very clearly knackered. The owner puts him on the lead and goes to leave the park. The man insists the dog owner needs to pay for a new car as the damage is her fault. The dog owner says she warned him about the car coming too close to her dog so he should've picked it up until they'd walked past the dog. Therefore, the damage is his fault and she won't be paying.
So, who's in the right? And WWYD?
