Emma, the manager of Tiny's Sandwich Shop, took a phone call from a customer
who complained of diarrhea and vomiting after eating a tuna salad sandwich the day
before. Emma was not worried about the complaint, but she interviewed the
customer for details anyway, documenting her findings. After several more calls
like that one, she knew there was a problem. Emma threw away all of the tuna salad
so no one else would get sick. Then she called her local regulatory authority for
guidance. While she was waiting for the authority to arrive, she made a list of the
staff who were working the day before.
