Run away from hospital

There's a patient ran away from operation room a minute before he has to do surgical.

"What's wrong" asked the security. The man explained,"I just the nurse said 'calm down Sir, this is just a simple surgical, everything will be fine".
"She just  wants to make you calm Sir. Calm down Sir, no need to be worry," said the security.

"But he didn't talk to me, he talked to the doctor."
