'On a more serious note....Why did they feel the need to SHOUT ACROSS THE OPS ROOM WHEN THEY HAVE SPENT A LOT OF MONEY INSTALLING COMMAND LINES? Not very professional!'
Because when you are trying to pass a bit of urgent information to somebody already making a call it is quicker to shout it and get a visual acknowledgement that they heard it than to wait for them to finish that call and then pick up the your one button out of the 20 that are flashing at him at the time. Also quicker than setting up a conference call if more than one person needs to hear it. Delay and you could cost lives!
If you are serving why not organise a trip to visit to them and understand the problems that they have. If your not you will probably still get a visit only without the juicy bits.
Damn - someone else got there before me!
