I like to go in on Sunday evening when theres no one in there but some stupid kids, most of the time they will give it to you. Another big supplier I've found is Grocery stores with a Deli, however, I always look to see if they have a nice new container with a good name on it, most of these are under contract. I've never been able to get any chain restaraunt to give it to me, they just don't know, they always tell you something about "its handled through corparate, I just don't know".
