Burowski ran an office supplies business and donated one evening a week of her time helping run a bingo for charity. There, she met another donor, Adams, an investment broker. They worked well together for a few months. One evening, Burowski said to Adams that she was rather confused about her investment portfolio; she wondered where she might get advice.Adams suggested they have a coffee together after the bingo hall closed. They spent about an hour discussing Burowski's portfolio, and Adams made some suggestions about how she might improve her holdings. Burowski suddenly remembered she was late returning home to her babysitter and left quickly, thanking Adams as she got up from the table. A week later she received a bill from Adams for $$150$ for "professional advice."$*$
