My grandmas old falling apart trailer had a gas stove.

They only moved out and into an apartment with an electric stove when their water heater fell through the rusted out floor onto the ground beneath the trailer.

Anyone who owns a home for more than a decade or two, which was pretty normal for the middle class (in the US) for a while, has to replace a stove at some point, and these aren't that much more assuming you already have a gas line.

Speaking of which, in many places, especially those powered by natural gas, these stoves are actually cheaper to run than electric ones, making them much more common.

But yeah if you see someone putting in their own gas line these days just because they want a gas range, they probably have some fuckin' dough.
