I have had the wrong way up two way light switch complaint.
On one occasion the other switch was in the garage, the husband of the lady telling me I had put the switch on upside down had a smile on his face as I tried to tell her there's another switch behind the tins of paint on the shelf in the garage. As she told me, they had lived in the house for over twenty years and she knew there was only one switch. Her final words on the subject were "I see you fixed the switch, I thought it would take you longer that that" her husband still had a silly smile on his face.
