Thats why I opened my own shop. Now I am on the other end. The way I have solved the problem is to have staff who's equipment and diving philosophy is compatable with mine. That means that I trained them. Our first year we had a DM who had worked many years for the shop that used to be in town. We dive all year. We are cold water divers. People who dive with us on a regular basis must move into a dry suit early on. This DM has plenty of money and time and dives mostly Caribbean. I found out he was advising people against diving local and dry. I tolorated him usung old obsolete equipment of brands I didn't sell but... I was compensating him to sabatage my buisiness. The DM may work cheap but I invested my life savings to work for free. Being part of the staff means being part of the team. The alternative is to simply find another team.
