Yes, this is becoming far more common these days, and I wish there were a way to teach people good manners and teach divemasters to calm down a little with this herding stuff. This is a good post and a good way to help spread the word. Most of these types of comments tend to be focused on nationality, but it's not about that; it's about attitude of the shop and about the divemasters reminding and teaching people good behavior. That's their job after all. Word of the day: Politeness. Help spread the word!
