We would
not have this post if there had not been an instructor present. I was indeed under the assumption that an instructor, even while acting as a dive guide (that's after all what I and the other guys paid for), has some amount of responsibility for the group. Especially when there are new divers on their first dive. I guess I was wrong with that assumption, having never dived without a paid professional as a buddy or guide.
But what role and responsibilities does a instructor/DM/dive guide then have? Plan the dive properly? Assign buddy teams? Or just lead the way to the best spots on the reef?
As previously mentioned, the initial mistake was made when the instructor told me to tag along with him and the other pair. If the other pair was not doing a class, the instructor was my buddy (implied). If he did do a class, then he should have not allowed me to go with him but stick with the new pair, right?
So the mistake I made was to not ask him whether he was doing a class. I am well aware that I am responsible for my own safety as well as my buddy's (if I have one
) and I was never in danger (or more than an arm's length away from the instructor).
I guess I am projecting my own feelings/fears on the situation of the new divers and how I would have reacted. Getting into problems under water on the first dive would have unnerved me. Not having a SMB for safe surfacing in a heavy-traffic area may have added to this feeling.
I am still impressed by the pair's disciplined behavior, probably because the worst that has happened to me so far was a loose tank...
Anyway, I thank everybody for their criticism and opinions. I do believe, though, that there are many divers out there that make the wrong assumption like I did - that a paid dive guide/DM/instructor on any non-class dive is the "boss" and has some amount of responsibility for the group of buddies.
