Here is a picture showing an attempt to try to
plug our hair dryer into an electrical outlet in
a hotel room. The outlet is just below the mirror
over the sink.
You can't plug it in
up-side-down (as shown) because the mirror
is in the way.
You can't plug it in right-side-up either because
the wide prong on the plug
won't fit into the narrow slot in the electrical outlet.
The electrical outlet was installed up-side-down.
When you design an object,
you need to consider the environment that
it is used in.
