OK, you are at the shore of a dive quarry. It's a nice day, but water temperatures are in the high 40s on the platform. Visibility is around 5-10 feet. Next to you, you see:
1) An experienced cold water diver in a dry suit. He is planning a no-stop solo dive in a non-overhead environment to CESA depths with a single tank and no redundant gas supply.
2) A couple wearing wetsuits. Both recently certified, both fumbling with their equipment, trying to set up their gear. You overhear one say to the other "just stick with me, and everything will be fine, stop WORRYING so much!".
Which diver(s) do you approach? Which ones are at greater risk? Leaving aside the legal implications of the quarry operators liability, rules, and future access, which one are you going to feel worse about if there is an accident?
