scuba privacy

What privacy rights do you have when you purchase something from a store, or pay for lessons? Should a store owner just turn over all of their records when faced with a subpoena? A scuba shop in Beverly Hills was issued a grand jury subpoena asking them to identify everyone who had been given diving lessons over the last three years. The Electronic Frontier Foundation (EFF) was asked for help by the store, and let the U.S. Attorney's know that it intended to oppose the subpoena in court. The subpoena was dropped.
