It does happen, there are charter operations that leave a lot to be desired or are downright dangerous, and everyone has the right to impart information or relay their experiences about any dive op. Do with the information as you will or ignore it as you wish. Unless you have a vested interest in the dive shop being discussed, there is little reason to malign a poster's credibility.
