Darwin was right...

I'm actually a fan of the British style plugs.  Lots of metal on metal contact, ground contacts first and these have switches and indicator lights.  The 240 volts still gives me the willies as we use 120 stateside and there can be a much larger "pop" when plugging things into the socket.  With the larger diameter holes than the slotted USA system, it is easier to use a bare wire rather than an actual plug.  This sign was in our conference room at the hotel and it looks like they may have a problem as many of the customers come in from the rural areas around Kumasi for events.
