Well It's pretty common knowledge that MD's are beholden to the community in many ways.
Their obligations include, but are not limited to:
-Organizing/setting up frequent matches which are scheduled for a day a specific shooter can attend.
-Matches must be of a format that is easy to shoot or at least cater to a specific shooters perceived strong points.
-MD's must prevent rain, cold, excessive heat as well as wind. Breezes are okay, but only if southerly.
-MD's are solely responsible for any delay that might cause the match to run longer than expected thus preventing a shooter from getting home in time that he may please his wife, attend a previously scheduled family get-together or a second match at another range/gun club.
-MD's may also be required to explain over and over again the CoF because shooters aren't really responsible for paying attention the first time. Doing so would interfere with the their banter regarding what gun their buddy brought and how its running, who did the work on the gun and how the gun is making its first appearance at a match, but worked fine when it was tested the day before with such and such ammo.
-Food. Yes, some are of the mind that MD's are also responsible for feeding the shooters that take time out of their busy lives to come shoot the match.
I'm sure there are other points, but these are the few I could come up with at the moment
