I think a number of posters have never dived in Cozumel and don't realize how DM's are required to lead dives and maintain some control over the group at all times. I assume that it is because the currents can be treacherous. I used to work for a school district that had two employees on vacation who drifted away from the DM and were never seen again. The theory is that they got caught in a sudden downdraft that they did not have the skill to extricate themselves from.
Still, I have seen the problem described here happen many times in Cozumel, and I have never seen a DM handle it like this. In fact, I would say that almost all of the DM's I have seen handle it routinely without controversy. They send a surface marker up and send the hoover and buddy up while the rest of the group continues the dive. The boat picks them up as soon as they surface.
