So it is likely useful to read all of the rules...
RULES AND REGULATIONS
That was an interesting read.
I want to say my 2 'orientations' were about 30 seconds in the shop of "stay off the coral".
I will say the 2nd shop I used - a larger op with a couple of tank pickup/drop spots - did ask us to do a shore dive on their shop, and watched from the beach to see if we resurfaced to ask for more weight - even though we were confident of our weighting...that's almost a check dive
I can't imagine these shops putting a DM in the water for a check dive for every visitor. It would be labor intensive.
This last visit I think the orientation was even less about anything in the water and more "have these tags on your person if you are in the water - even if snorkeling" and "if you go up to the park - don't forget your paper receipt to get in without paying - it's a long drive back."
As I think back to it - they also had multiple receptacles for trash fishing line collected from dives.
Rebel scum.
In all seriousness about the staying off the coral bit and orientations. I won't lie, I don't always enjoy having a finger waved in my face to remind me of the rules particularly when I consider myself conscientious. That being said...we've al seen that guy hugging the reef with two gloved hands - a fin wedged in some place - trying to stabilize himself in some current so he can get that perfect shot of the juvenile whatchamacallit that he is focusing on right now. I suppose if you don't at least start with wagging your finger at everyone, that particular moron has the plausible deniability to say "wha? that's a problem?" when someone tells him "hey dude, you are acting like a jack ass.".
I've seen that guy in a number of different places...and as a percentage of divers I've seen, he does show up less in places that actively tell you not to do these things. In Okinawa that guy was like 1 in 6 divers.
Any ways - I'm off topic and ranting. Bottom line - I didn't know about the rule - and remove the advice. I'm sure if you got caught breaking the rule there would be a hefty fine involved.
That being said - if you are going to do it...
1) find a spot without coral.
2) make sure the current isn't going to push the line into coral
3) don't leave it behind
4) don't get caught.
