Was installing a vanity light over the bathroom sink in an old apartment complex for a friend, the original fixture was a florescent fed without a box. I told the grunt that X marked the spot and cut me a 3 ½ inch hole for an old work box. Grunt comes out of the bathroom smelling like a port-a john and advised me that he had found the waste line for the units upstairs. I cut my own holes since this time in old work.
