At least in the US, just about every outlet has a ground port (Type B), even if the device you’re plugging in has only a 2-prong plug. I’ve only seen the Type A outlet in one really old building.
Lots of old houses in the US still have a bunch of the Type A outlet. My first apartment did for most outlets.
Now, what’s really fun is Knob and Tube wiring, where the hot and neutral lines are separate wires. Which means they tended to be run in separate directions if it was convenient for the asshole from a century ago to run it that way.
Does Finland use C outlets, though?
