As a seasoned home depot employee, I have to throw in my .02 and say do anything you can to get the mdf cut without having home depot do it. Whenever someone asks me to cut some wood for them i tell them that i'm late for my break and if they can catch me in 15 minutes ill think about it. After 20 minutes i will come back out and hide from them. If for some reason i actually do have to cut the wood, I will measure the cuts using the measurement tool that is attatched to the panel saw itself (it is off like 3/16's). The reason i do this is that people ALWAYS ***** and complain when i tell them only the first 2 cuts are free, after that its .50$ a cut. "AHHH, thats crap, back when I was a kid you could get as many cuts as you needed, it was called customer service, infact, back in '56......." Well *******, here are your free cuts, and just remember, nothing in this world is free. I'm done.
