“Guy’s” name in this thread was not “Guy”. So any guy named “Guy” is not the guy this story is about."Guy" may just be too cheap to pay for Nitrox. If that is not the case, then he is an ignoramus. Unfortunately for me, introductions on future dive boats might be a bit stressful: I too am an old guy named Guy, but I'm not that "Guy."
My apologies to anyone really named Guy.
