We are, for the most part, a self regulating industry. When something like that comes up there a re a couple of things that could/should be done.
1. Talk to the DM and have him/her have a chat with the offender.
2. Put on your Deputy EZ 2000 hat and be the SCUBA cop. That is if you are comfortable having the chat yourself.
3. Point out the situation to a more experienced diver and ask them to watch on the next dive. They might feel more comfortable in the SCUBA cop role.
