Man sues flowershop for sending his wife a copy of the card he sent his girlfiend

He might actually have a pretty good case. There are privacy laws in place, and most merchants aren’t allowed to share ANY information about a customer or transaction unless it is specifically authorized by the customer in question (or has been properly subpoenaed by the court system). Try calling Wal-Mart and asking something along the lines of “My wife just came through your cashier line and made a cash purchase. What was it?” Wal-Mart (and just about any other large company) would refuse to issue you any information because of the potential legal ramifications.

Of course the guy was wrong to be cheating on his wife, but the courts won’t look at it from that perspective. They will only look at whether his privacy rights were violated.
