The operative word definitely is 'supposed' to check.
Rarely am I asked to show my TDI cert, so you can
get away with a lot if you're so inclined.
But I've been in a variety of places and have found
operators to be pretty good about enforcing this
practice. The main method is the nitrox logbook,
in which the tank serial, pressure, mix, max PPO2,
mod, agency, and signature of diver are required.
I imagine this is driven by insurance, but it
serves the purpose. In many cases, the DM does the
analysis under the eyes of the diver. They seem
to have a problem with O2 analysers walking off.
So I've been in shops and boats in Monterey, the Lois
Ann in San Diego (which has a large storage of 32, but
still does the checks), one shop in LA, and a resort
at Roatan. And one shop in Vancouver. No one has
glossed over it yet.
