I was going to stay out of it, but I just can't. Part of this is the PITA fee. When you come on the boat, we're happy to give you a band aid when you need it, a couple of aspirin when you have a headache is fine, A cyalume is necessary and right, batteries?, yup, no problem. What, need some O2 for your bends, here ya are. Now. All of those things need to be replaced. Some crewmember must go to the store and get aspirin, band-aids, batteries, cyalumes, etc. Is it dififcult? No, not in Key West, but I'll bet it's a different story in Chuuk. Oxygen is likely an extra pain in the butt. You don't just drop off your jumbo D's at Airgas and pick them up on Tuesday. Because you need them back on a 12 hour turnaround. On the weekend. Otherwise, you go back out without. And that's not safe. So, someone in the crew, probably Lance, has to go find some O2 and a booster, and a fill whip with a double pin connector on a Saturday when it's the only day he "has off". And he's already a little miffed because your friend got bent, sucked down 3 days of O2, and returned to diving all without seeing a physician or even a hyparbaric tech.
That's why your friend paid an extra $600. He can get it back from his insurance company. Lance has his PITA fees covered. Everyone is happy.
