The only commercial kitchen stove I interact with on a somewhat regular basis is a miserable piece of crap. It has multiple pilot lights, some of which go out frequently and stink up half the building with unburnt fuel. I suspect that just the pilot lights consume $50-$100/month of natural gas.

Stoves seem to be somehow special in safety regulations. I guess regulators assume that they are never operated unattended, so they tend to have no real built in safety features. Both commercial and residential stoves will happily operate unlit at full power.
