I know, but to me it's a pretty silly and pointless "request". It's like asking Ford to build a new car.
By you "asking politely" isn't really going to get them done any sooner.
Look at it this way, you bust your butt all week to get a project done at work a week early, and all they have to say about it is "how come you don't have that other stuff done?" Makes ya feel all warm and comfy inside wouldn't it?
