re: Which outlet is correct?

The electrician I used a while back put them all A, except for one. It was one up high on the wall in the laundry room. I asked him the next time he was out if he had done that on purpose, like if one up high there was a legit reason to have it flipped. He just laughed and said he must have been tired by the time he got to that one. He offered to flip it over for me, but I told him not to worry and I'd get to it.
