Yesterday I was on the public London metro with my son and we got on the same carriage as I blind man with a Pomeranian service dog taking a seat next to us. My autistic son shot up touching the dog I got him back and sat back down. The man raised his voice at my son screaming at him saying DONT TOUCH THE DOG and NEXT TIME HE WILL BITE YOU causing the dog to start barking loudly which made my son start crying and having an autistic melt down on the public train. I was completely shocked and raised my voice back at the man telling him he had not right to raise his voice and scare my son. The man didn’t reply and sat down getting of the train in 2 stops cursing under his breath during the whole ride.
