A and B Entered a Variety Store Owned ByC

A and B entered a variety store owned byC. A purchased two chocolate bars from C, and gave one toB. Unknown to A, B, or C the chocolate bar which A gave to B contained a piece of metal that had fallen into the chocolate mix when the candy bar was made. When B attempted to eat the chocolate, she damaged one of her teeth. She was obliged to have the tooth repaired by a dentist, and in addition, lost a day's work because of the painful injury to her mouth. Her total loss amounted to $300.00.
B was careless in eating the chocolate bar, and therefore was responsible for her own injury.
