The Office has 1 door, a window and a hallway so this makes sense.

Freaky - He will slowly move down the hallway, use the flashlight on him for 2-6 seconds depending on AI level. He can also use the vent to leave the hallway and appear at the door. If he's at the door, close it.

Rose - She will move around the restaurant placing flowers, if she's managed to place all the flowers she will move towards the office and will start smashing the glass trying to break in. You must destroy the flowers to stop her from getting to the office. She can be flashed with the flash light to stun. And the glass wont repair till the end of the night.

MeatMan - He will be on cam 1, after a while he will start moving towards the office. Stare at him to halt his movement and stare for 10 secs to make him go back.

Ghost - They will slowly appear in the office window, use the flashlight to make them vanish.

Max - He will start in the bar and go towards the office. When he gets to the door close it. If he goes to the window and pulls out a glass of beer, click him.

Pop and Bang - Pop will appear in the office, once they appear in the office, Bang will begin going towards the office. Simply click Pop to give them back to Bang. If Bang reaches the office, either close the door or quickly return Pop. However, if you use the door, Bang will only go back a little bit.
