Even with proper valid certification document (PADI Rescue Diver-33 dives), properly maintained Dive Log book and only 2 months since the last dive I was required to perform a refresh or a local dive before being accepted to go on a day trip. This scam is used to have divers spend more. Feedback from the operating manager was that you need to be "instructor" level to go directly on a boat dive. What is the use of the certifications then? Is the operating manager worried about our safety or about his bank account?
