Clearly re-cycling helps the environment. Just becasue it may be inconvenient does not mean that it is not a good thing to do. My original comment was a suggestion that I thought it would be a good thing to do.
Indeed, it would be a good thing to do, however...
Since this was your first liveaboard trip and there were a lot of distracting disappointments beyond ExVen's control, you may not have noticed how extremely hard your staff was working. More so because there were too few of them (that would be due in part to starting understaffed, which is the only thing in your story I can see blaming ExVen for). I've been on that boat several times, including six weeks ago, and have noticed that nobody on that boat has more than fleeting moments when they're not working.
They do everything from assuring you're fairly together when you get in the water, to cleaning the toilet in your room. They bus your table when you're eating, they clean the boat when you're diving, they are constantly available for whatever you need whenever you need it, always available to chat, take special requests of any kind if humanly possible, etc., etc.
My point is, yes, it would be nice to recycle and I cringe a bit over that as well, but geez, they're already doing SO much. I don't know where in the day they could make room for another task. They already work way harder than I would ever want to.
I've been on the boat with Captain Ken and am aware of his seemingly casual approach. Don't be fooled by the exterior during routine moments. I saw him spring into action when some divers got lost on a night dive (two separate, lost groups, no less). He was serious as a heart attack and all over it until everyone was back on the boat, safe. He was one of two crew out in dinghies dragging those fully-equipped divers' sorry butts over the edge without assistance. I also saw him manage a situation in which a guest got bent; you couldn't ask for better support during a dive emergency.
I am curious to know who got bent and under what circumstances on your trip. Those people were extremely good to me on my trip, and I'd like to wish a full and speedy recovery to whomever it was. I don't want it to have been anyone, obviously, but I'm hoping it especially wasn't Tim, who went way out of his way to make my trip one of the best I've ever had.
