I was quite starved one night but was way too hammered to drive anywhere and didn't have anything in the house at the time -end of the shopping cycle- so I found this Carl's Jr super star in the backseat of my car, it had been in there for a bout a week -got it on a road trip camping- and at the time it seemed safe to consume so I peeled off the lettuce and wiped off the gungy mayo sauce and chowed down. Back then I had a cast iron gut so no nasty side effects.
