I can say what I usually do and it works great for me, First thing is to always be early so no one has to wait on you and ask permission to board to make sure the crew is ready for you, then try to start to setup your equipment before you even get into the water, I also always try to locate the rinse bucket and pay attention to any dive briefing from the crew, also I carry some cash so I can tip the crew after the dive is done.
