So I'm going to know to unplug a dryer and expect my friends to be cool with that? And that plug is plain out in the visible, easily accessible areas and not hidden behind a heavy dryer?
People often don't have a dryer in the garage, but it's common enough that they'll have the plug there anyway.
I've owned half a dozen houses including new construction and never had a 240 outlet in the garage.
I wonder if it's a regional thing. My experience is US West Coast. The dryer is a source of waste heat, which out here is usually undesirable, so it makes more sense to put it in an extremity of the house where the heat can easily escape. I could imagine that other areas of the country might be more likely to view extra heat as a good thing.
