With gas prices going through the roof, it makes sense that you'd have to start worrying about getting your gas siphoned by thieves. But it looks like fast food restaurants are going to start finding their tanks empty as well. David Richardson, an employee of Restaurant Oils of America, was caught pumping out the storage tank of a Burger King with which his company didn't have an account. His 5000-gallon tanker truck was half full of cooking oil, so it's unclear how many other unauthorized siphonings he did. He then transported the oil to a recycling center in California that pays more per gallon than recyclers in Nevada. Restaurant owners normally have to pay to have their old grease hauled away, so it's the company Richardson works for that's actually taking the hit here.
