Just came off a loooooong week with a couple of divers. For every single thing they did 'wrong' the next words out of their mouths were:
"Yes, but..."
Grabbing coral, harrassing wildlife, kicking coral, going too deep, running very low on air, going in to deco, zero buddy awareness....
One of the divers is supposedly a PADI IDC Staff Istr + TDI with more than 7000 dives (her words). The other was her student with about 30 dives.
During the check-in the first question was about how deep they can go. The second was about getting a discount. When asked where they can buy shark's teeth, I had to reply..... in Russia. Haven't had divers like that in a very long time.
My personal favourite however was another guest a few years back... also from Russia... who went in to deco, didn't do his stop, and his D9 shut him down for diving. His comment was...
"I think computer.... mistake".
