In the mid-eighties, I was the right of way inspector for the highway department. Any utility work, or private improvements done in the State's right of way, I inspected. I was watching a contractor install a new sewer line. Bottom of trench was at 8-ft. Phone lines were at 3 to 4-ft.
He called the dig-line and requested locates. As we got close to one of the intersections, the phone marking was there in orange spray paint. Twelve feet away was a depression running across the highway, directly in line with two large phone company pull boxes in the sidewalks of the side street. I had been there with a state crew two years before to put in traffic signals and add turn lanes to the cross street, and we had moved the curb and gutter 12-feet as part of the project. The contractor spent the entire night going slow, and hand digging the five feet both sides of where the phone company markings were. By the time he finished, it was almost quitting time, so the contractor called it a night, and I suggested he call the phone company for a field meet, to discuss the line location.
Next night, the phone company locator shows up drunk, cusses out both me and the contractor, and insists that the line is where he located it, and if there is anything where I think it is, it is abandoned.
Contractor lowers the earth saw and away we go. Right where I thought the line was, colored wire starts coming out in the spoils. The contractor stops and asks me what to do. And, I responded, "He said if there is anything there it is abandoned. Go ahead and get clear of the mess." So, the contractor started back up, and about twenty minutes later the phone company trucks start showing up.
After about half an hour, the foreman for the phone company approaches the contractor and ask if he has any idea how much this is going to cost him. And I interject, "Not a Damned dime. Your locator mis-located the line. He lost a day's production last night going twenty feet, because he hand-dug both sides of where the location marks are. He requested a field meet and relocate tonight. Your locator showed up smelling of alcohol, called us stupid bastards, insisted his marks were in the right location, and informed us stupid bastards, that if there was anything where I thought it was, those lines are abandoned. So, when the confetti started coming up from your "abandoned line", he just kept digging." I then informed the phone company, they needed to get traffic control in place by 0600, and to let the media know there was a major lane closure.
We had cut through all the lines for the south half of Las Vegas, and two fiber optic lines. Took two days to get everything back together.
