Blind man claims he was turned away from restaurant - because of service dog

A blind man claims he was turned away from a restaurant - because a worker didn't believe his service dog was legitimate.

Paul Castle made the allegations in a post on Instagram earlier this month.

He claims the incident happened at an unnamed restaurant in his home city of Seattle, Washington.

Paul says he walked in and a waiter quickly approached him, telling him no pets were allowed in the restaurant - including "emotional support dogs".

Paul says he showed the waiter his dog's harness and offered to get his papers - proving it was a service dog - for proof.
