A reader sent us the contents of a Better Business Bureau complaint filed against Taco Bell. It describes how a customer tried repeatedly to find out what grade beef Taco Bell uses in its food, and how nobody at the company was able or willing to provide an answer. Not surprisingly, the BBB complaint also went unanswered. Let’s just hope they’re not sourcing their beef from forklift cattle, which is like downer cattle but has odd prong-shaped bruises on the side.
