The instructor on our dive boat last weekend was telling me a thing or two about DIR divers in his experience. I am going to redact the text slightly to avoid getting flamed, but this is the gist of it:
"Well, the thing about DIR divers is XXX XX X XXX XX XXXXX, XX XX X XXXXX XX XX XX XXXX - XXX XX "XXXXXX XX X XXXX" - XXX XX XXX XXXX XXXX XXX X, XXXX XXXX XXXX XX XXX XXXXXX. They all XXXXX XX XXXXXXX XX X XXXX XXXXXX, and never XXX XX XXXXX XXXX, XXXX XX X XXXX XXXX XXXXX. But I tell you what, they are good tippers."
Hey, what were the XXXX's ?
