I feel the same way. We were moritfied in Jamaica, when we were snorkeling and they told us to stand on the reef to get our bearings. How horrible. We do look don't touch too. If only everyone would realize the importance of "look don't touch" then we'd have these reefs to dive on for years to come.

No lecture here, sorry to suggest it. I just recently saw that for the first time and it shocked the heck out of me. The other places that I've snorkeled/dove (Hawaii, TCI, and Bali), they were very strict about keeping your hands and fins to yourself.
