totally agree, i work for servisair at MAN at the moment, and we had an example of this the other day with a thomson 733.
I was working on another stand, and had to wait for a thomson 733 to come on stand and shut its engines down before i could cross behind.(same example per my origional post)
I was waiting about 5 minutes before i lost my patience. I could see the ground crew looking at the cockpit if to say "what the hell are you doing!!", so i pulled alongside a literally screamed "THEY NEED POWER!!", they couldnt thank me enough.......
BTW when meeting and greeting an a/c, connecting power is the second thing we do after chocking. Remember at MAN the power cables are connected to the air bridge, so connectivity time is governed by how quick the dispatcher is....
