OK, a bit of a twist in the orignal posters question, but what about tipping DM's who assist in-water with a class thru a LDS??
I've only been "tipped" a few times when helping out, and it is not expected on my part. Everything from cash to a case of beer and a bottle of rye. Those few times I've been tipped with cash occurred when the instructor(s) thanked the DMs at the end of the classes and told the students that the DM's help was all voluntary. The first time I was passed some cash surprised me all to heck and didn't really know what to do!
When it has happened I've just assumed that in the eyes of the folks that gave me the tip I must have done something to make an impression. The gesture certainly makes an impression on me when it happens.
