Growing up in the U.S. Ive never been able to shock myself plugging in a type A or B connection. 35 years in and never met someone in person who had ever complained about doing so. Now dryer plugs annoy me. They are the 220/240v, and I know there are at least 3 different types. So I’ve had to swap the power cords on the dryer in every place I’ve lived in. (I just keep the old ones). But if you rent a place built in 1970, 1985, and 2010 (random dates). They will all likely have different outlets.

Usually it’s from a lack of maintenence causing the receptacle to loosen leaving part of the plug exposed.
