In the ex-USSR there was usually no grounding at all. All plugs had just 2 pins. Even if the socket is new, the wiring most often isn't.
Everything works mostly normal, except that you can have 110 (220/2 via capaciator bisection) volts with large impedance on "supposedly grounded" metal surfaces to give you minor shocks/uncomfortable feeling.
