If you don't work at the FIRE STATION and you happen to be there when a FIRE ALARM SOUNDS ... you'll have to get out of the WAY and you'll have to excuse the way that EVERYONE IS MOVING FAST because THEY KNOW there is a fire ... and they hear their CHIEF shouting ... He's YELLING ORDERS!
Men are MOVING FAST!
If you are not a Fireman there... you would think the Chief is harsh ... because you don't understand the URGENCY and you're NOT a FIREMAN submitted to the CHIEF.
