There's no reason to cringe if the diver is using air.
Yea... but who'd do THAT???

1. The narcotic value of air is higher than any other commonly available breathing gas.
2. The extreme amount of intert gas in air increases its risk of DCS on shallow dives
3. Air has an incredibly poor value as a decompression gas.
4. Because of the different grades of air, using it may contaminate my oxygen prepared tanks necessitating recleaning (expensive and time consuming)
5. Better breathing gases are available for a minimum cost premium in many cases.

Cost for air fill: $4
Cost of Nitrox fill - 32% $10.00
Cost of Nitrox fill - 36% $12.00
Cost of Nitrox fill - 40% $15.00
Cost of Nitrox fill - 50% $20.00
So for the same money I can dive at least 2.5 times more often, not even counting the O2 cleaning cost. Additionally, the vast majority of dive boats here fill air and not nitrox (the Peace is an exception).
I'd say for the type of diving that most of us do, that's a pretty compelling argument.
