Keygrip,
The problem with giving all the small aircraft intersection departures and all the large and above full length is that each time that large rolls I have to give the small aircraft a 3 minute wake turbelence delay.
My best option is to take the small aircraft to another runway to avoid the wake turbelence delay, my second option is to take the small aircraft to full length.
I as a controller am not going to hold up large full length departures because a small aircraft requested an intersection departure, and my ground controller had better have the common sense to take you to full length or to another runway, or to warn the small departure that there will be a delay from the intersection.
As to requesting a minute for the wake turbelence to dissapate, that isn't a problem unless you are at a busy airport where they are constantly having to shoot gaps between arrivals. Again the key is to let the controller know soon enough that you want a slight delay. If you are in a line behind large aircraft waiting to depart, you should know right off whether you want a slight delay, so tell the ground controller, or the local controller as soon as possible. I would much rather have you pull off to the side so someone else can depart than to have you hold up the departure stream.
The only time that I get testy with a pilot is when I'm shooting the gap between arrivals and the pilot takes his sweet time taxiing into position and hold, or I've cleared the pilot for takeoff and they just sit there while the traffic on final bears down on them.
