INZ--I'm just curious. Is it that Eduardo wasn't as chatty/friendly as some of the divemasters, or did he say or do something that struck you as unresponsive or disdainful or something? If it's the former, I wonder if that was just his manner, and not necessarily his attitude toward newer divers. If it was the latter, well, that's not at all good. Either way, and speaking generally, DMs should be more than "tolerant" of newer divers--they should also be looking out for them a bit. And the best of them are excited to see you excited about diving. I'm not here to cheerlead for any shop or DM--we only did one day with Eduardo, and Scuba Mau isn't our most regular op--but we did find them very responsive and eager to hear of any issues a diver might have. I'm glad the bulk of your experience was good.
