I don't want to turn this into a PADI bashing thread (hah! fat chance) but I never understood the PADI requirement that for 5 star rating the shop must not teach other courses which are available from PADI.
Does that mean (say) if a dive shop offered TDI Advanced Wreck, then that is OK (as PADI has no equivalent course on wreck penetration) but it would be wrong to teach TDI Advanced Trimix, for which you would lose your 5 star rating?
