Staff changing room

The chubby man dressed in blue walks down the corridor to the staff changing room.  Inside there is a row of lockers on one wall.  On one of the locker doors is a laminated note: 

ALL WHO ENTER THE HOUSE OF MASKS MUST BE NAKED, MUST WEAR A MASK AND MAY NOT TALK.  THIS APPLIES TO ALL WHO ENTER, BE THEY GUESTS, VISITORS, STAFF OR DELIVERERS.  YOUR MASK IS IN THIS LOCKER.

POLITE REMEMBER: YOU MAY NOT TALK ONCE YOU HAVE DONNED YOUR MASK, PLEASE MAKE ANY NECESSARY ARRANGEMENTS TO COMPLETE ALL TASKS WITHOUT TALKING.

The chubby man dressed in blue does not hesitate.  Undresses briskly placing the blue clothes neatly in the locker.  Dons the CRAB mask and steps through the door to wait in the corridor.
