Yep, and they will lie about it. The last time I was on a liveaboard, the director of diving made two false statements about the limitations on our diving, and both times he said they had no choice, because those rules were PADI requirements. Leaving aside the fact that PADI has no authority to set requirements for liveaboards, in neither case was the supposed rule a PADI policy. Not wanting to make a scene, I talked with him about each rule, and he admitted that it was company policy, and it had nothing to do with PADI. He did not say this, but it was obvious that by saying they were PADI rules, he could get the customers to direct their anger at PADI, not the company.
