I have been on several guided dives where my buddy and I (and others in the group) ignored a dive guide who either (1) took off like a rocket and never looked back, (2) invited us to do something we thought was wrong (petting a grouper he was holding captive), or (3) was going to do something we thought was unsafe (120 ft to see a cross in a little cave). With #3, most of us stopped at a tad over 100 ft, shook our heads, ascended to 80, investigated the wall, did our safety stop and got back on the boat. The guide's "buddy," a 70+ sometimes diver, ended up with the skin bends.
Our core group is all experienced divers, all retired. We liked returning to the same places because we have favorite dive masters who know us.
i would have considering seeing the cross in the cave myself -- if it was visible from outside the cave with a light & the depth was within my mod & dive plan (including enough redundant gas) -- otherwise i'd have done the same as you... if they planned on entering the cave at all -- not a chance..
