gonetobaja.........don't forget...some of my favorites...I agree with you!!!!!!!!
Lugging tanks
Dealing with divers that complain because their EANx is .1% off from the requested mix
Lend out a spare BCD because of a sticking inflator
Don't forget replacing rotten, broken mask straps, and fin straps
Hooking up the forgotten inflator hose
Going under water, and removing fins for out of shape divers that can't do it themselves
Hauling their equipment on board because they are too out of shape to climb the ladder
Lending out your spare mask because someone forgot theirs
Lending out your divelight for the same reason
Turning on their air, because for them, it wasn't a priority
Showing them how to setup their computer because they didn't have time to read the manual
Teaching dive tables for the 10,000th time
Helping fat divers out of their wetsuit while listening to BS about how they used to dive with Costeau
Retreiving a weight belt FOR THE SECOND TIME
Retreiving fins, masks, snorkels dropped under the boat
AND...cleaning up projectile VOMIT!!!!!!!!!!!!
And my all time favorite was the free flowing regulator...that when the second stage was opened and there was a wasp nest inside. Of couse the customer swore the regulator was "just serviced last week".
Try it once and you may even appreciate the job your divemaster does, as he is actually there for you. If you don't think this is a service then you should be running your own boat. And if you're too tight to tip......at least say thank you.
