You probably should go there and film it yourself ;) And you probably should also say this to the owner of the video, not me. Just be happy and thankful that someone filmed this and shared it with us.

So please deliver my message to the person whose recording you're sharing with us, as it was meant as friendly and constructive criticism, from which one hopefully can learn and improve.
