George-

Read your post...you imply that for a store Nitrox is MORE DANGEROUS
than trimix. ("I can understand that someone doesnt want to do the more
dangerous Nitrox fills, but with Trimix...")

Your points about profitability are quite valid, but they serve nothing
toward your earlier point that Nitrox is more dangerous...I believe that
is what people were calling you to task on...

       >What's the dangerous part?????
       >Care to explain?

       Liability! Profitability! 
          1. If a business does not of significant demand for a product
they will not produce it. If a shop has 2-3 Certified Trimix divers that
frequent the
       establishment, it is not worthwhile to make the investment in
supplies and training to properly service this minority.
          2. Lets take a look at liability. A diver makes a dive on a
15/53 refill to 300 feet, he makes a mistake and doesn't come up. Later
it's discovered,
       after laboratory analysis, that the mix was really 15/48.
Narcosis may have been a contributing factor to his death. Can you see
the possible law suit?
       While Oxygen % can be readily measured, equipment to measure
Helium % is cost prohibitive and not readily available to the dive
industry. If you say
       cost bedamned see paragraph 1.
