He has this thing where he won’t talk to anyone, bar the most senior crew.
He treats everyone else like crap.
He thinks he’s above everyone.

“Martin Kove (who plays Kreese inTheKarate KidandCobra Kai).

The PA was in tears when he finally came out, terrified he had already lost his job.”
“The same PA was assigned to take him home after the shoot.
Kove said he wants to go to McDonald’s on the way back and apologized.

The kid said production didn’t give him any money.
Kove said, ‘I’m buying.
Sorry about this morning.
I don’t know what got into me.
Order whatever you want.’
The PA was so pissed, he said he wanted nothing.
Kove convinced him to get something.
At least a cookie.
My treat,' said Kove.
The PA said, ‘Alright, fine.
I’ll take a cookie.’
Kove bought the cookie at the drive through and got nothing for himself.
