We've mostly met nice people on dive trips, but occasionally you meet bores, talkers, or even jerks! Have you ever been stuck on a boat with a busybody that appoints himself an expert and makes it his business to chastise others about their diving technique? I don't mean quietly taking someone aside and offering helpful information when warranted, I'm talking about a loud, self-appointed, interfering know-it-all.
We were on a boat with one of these guys several years ago. His wife was clueless and dangerous and needed his attention, but he ignored her and watched everyone else and loudly told us whatever we were doing wrong, in his opinion.
Our last dive with him and his wife was a fiasco. It was a rough day and after I jumped into the water I found that I was dangerously close to the hull and being pushed closer by the waves. I know that I should have signaled "okay" to the divemaster on board but I didn't; I quickly moved away from the boat and went straight down because I was really afraid of cracking my head. I did signal okay to my buddy and the divemaster in the water after I submerged, but I recognize that I missed a safety step on the surface.
After the dive when we were back on board, the know-it-all started giving me a dressing down for not signaling okay on the surface. I acknowledged the omission but explained about the danger of hitting my head on the boat but he kept going on about it. I finally told him that it was none of his business and that "it's up to the divemaster to tell me if there is a problem with my technique!"
The irony of the story is that when his wife surfaced after the same dive, it turned out that she had gotten confused after a swim-through and had gone down to 150 ft on Nitrox. She said that she "couldn't figure out what was making all that noise" but it turned out that it was her computer screaming at her! She was furious when the dive op told her that she couldn't dive for the rest of the week. Neither of them came back and the rest of us didn't miss them!
