We had a leaking high pressure air line at the factory I work at. Production environment, so everything is fuck all compared to parts coming out. We went out at night and patched it. Next morning they said that we needed to dig it up and have all the new line laid out next to it so we can swap it over lunch.
I told him there was no fucking way because I needed to get a contractor out to scan underground for other conduit. Disclaimer: we knew for a fact there was no gas or electric lines where we dug. Well while digging, in the first hour, the backhoe broke the line in half. Called it.
Then we broke a water line. Called it.
Then a 14" sewer line. Called it.
Then internet cable. Called it.
Then factory communication line. Called it
Just finished that job with over 200 hours of holiday overtime. That'll teach em. Now to get communication contractors out on a holiday weekend.
