Oil Theft? Really?

I love Massachusetts and especially Boston. I've visited a friend who lives there probably 20 times. There's a funny gruff friendliness and sarcasm that runs through the general public when you're standing in line or in a public place. Love it! There's the mix of old style, old family Irish and Italian and then the more recent immigrants that keep the region spicey and interesting. So this article sparked my imagination about uncaught crooks stealiing of all things USED COOKING OIL. So this triggers my imagination. First of all I had a brief two week experience with restaurant cooking oil. It involved frying tortilla chips and sopapillas and attempting to clean up. I'm telling you grease was oozing out of every pore and dripping out of my hair by the time I'd spent a few hours doing this. So I'm trying to imagine the experience of stealing the USED cooking oil. This seems like a slippery, smelly, messy experience. Ripe for a comedy scene in a movie. Another thought that comes to mind -- I can't imagine you just dump this stuff in your furnace or car. Doesn't it have to be processed? So do you take home say 500 gallons of greasy goo and have to stew it or strain it or something? Do you do this in your garage? In the end is the effort truly worth the $1,000 that MAYBE you saved? Seems like a lot of work, stink, and effort for what is not exactly a grand haul. I don't imagine there will be a follow up article if they ever catch the culprits but I'd be curious to see the industrious thieves. I wonder if they will smell like old grease. What if they caught them because of the smell of processing or cleaning it?
