I will "argue otherwise" in a way that should make you reconsider that position. Reef Divers makes a big deal about a few rules. 1. Everybody dives with a computer. 2. If you lock out your computer by doing something like skipping a deco obligation, high speed ascents, etc., then you will be held out of the water for 24-48 hours until the computer clears. Without a computer with them, the DM has no idea what their 2nd dive profile was and no idea what their nitrogen load is at that time.Ignore him - in my experience here, that poster is often a sanctimonious blowhard.
By any reasonable measure, prohibiting the next day’s dives was completely unreasonable given the profiles that are dived there. Arguing otherwise is just ridiculous, in my opinion.
The diver forgetting their computer for the 2nd dive is one possible explanation the DM could accept. But if a diver locked out their computer and "forgot" to take it on the 2nd dive instead of admitting to locking it out, and then doesn't tell the dive master prior to breaking the rule and diving without a computer, that is a serious situation that puts the diver and the operation at risk on an island with minimal medical capability and no hyperbaric chamber.
Holding them out from the afternoon dive is a no brainer in that situation, because with no computer on the 2nd dive, the DM has no record of how conservative the diver's profile was or wasn't. In my mind, the DM could have looked at the computer to make sure it was not locked out the next morning and allowed them to dive after confirming it. But I am sure the DMs are suspicious any time a diver does something like that without talking to them about it. Given that it was the last day of diving before flying out 18-20 hours later, and not knowing what they did or didn't do the day before, there is at least a plausible, if probably excessively cautious, reason to believe the diver should consider not diving.
I am sure in the eyes of the DM, getting in the water and not noticing you forgot your computer suggests a diver who either didn't do their basic buddy and gear checks that should be a part of every dive even for experienced divers, or a diver who didn't wear the computer for the 2nd dive for a reason.
Regarding the vaping diver, I have been diving with RD at CB and LC for over 25 years and this is honestly the first time I have ever heard or seen of them being accused of doing something unsafe.
