You know this is a contributing factor for why some of us end up classified as angry,rude and worse.
You are entitled to dive with whoever you want, regardless of your reasons. For all I care, you may decide that you wouldn't dive with anyone that doesn't have a ribbon attached to the wetsuit zipper. But why "would have a nice long talk about safety" with anyone if that person is not to dive with you. If you approach me with that intention you'll get a swift "go away" assuming you caught me in a good mood.
People, when you are out there diving remember that not every adult you encounter is just waiting for your wisdom; some of us do what we do exactly the way we want to do it.
That also goes for the ones that don't go directly to the person for the "nice long talk" but go running to the capt/DM telling so and so doesn't have and octo. What is it? Are there boats where the capt/DM's give golden stars to tattletales?
I understand the OP is asking for the general opinion, and I assume will read the responses and draw a conclussion from there. It is a wonderful thing to give your suggestions when they are requested, but don't get the idea that it takes a village to raise a diver.
