+1 of the opinions that you're being taken for a ride.
When I train DMs they pay for their course and we do all the work together for every dive they assist with as part of the internship. In other words, if I haul tanks, the DMT hauls tanks alongside me; if I wash sand out of the truck after a beach dive, the DMT does this together wih me; when I clean up rental gear, the DMT helps. I don't ask the DMT to serve food, clean toilets, run to the store to restock refreshments, etc. None of that is DM work and is only related to the job in the sense that our divers eat the food, use the toilet, and drink the beverages. My DMs have to pay for boat dives that aren't part of the internship (i.e., if the dives are fun dives or are needed to get to the minimum dive count for certification), but even with these dives, I offer the dives at cost (about 2/3 off retail price) and I don't make any money on these DMT dives (the cost is something like $35/two dives on air at the DMT rate). If my DMT needs any equipment at all, I offer it at a professional courtesy discount (about 20% off). I don't see my DMTs as "customers" as much as I see them as "colleagues in development." Why would I want to cheat my colleagues?
