My fellow lawyer approached me today and shared a story.
Casual acquaintance of mine bought some meat & cooked it. The next night she and her son were eating the left overs when she bit down a piece of metal in the chicken. The piece was small - smaller than a fingernail. Her tooth was chipped and she had to make an emergency dental appt. In her naivete, she contacted well known chicken company. The "really nice guy" has been very helpful and sweet. She sent him the piece of metal per his request. She also gave several statements and answered all questions. He was very nice. He sent her a letter and told her that they ran it through their metal detector and it triggered the alarm. IE, Ergo, Therefore, it would have triggered the alarm before it left the hen house and ie, ergo, therefore, the metal must have come from her house especially since she was eating leftovers.
