I bullshitted a job after winning a bid I had thought I sent to the moon. Digging ontop of critical infrastructure infront of various engineers and contractors. I learned how to operate in a day and was proficient after two. I explained my lack of skill on the backhoe was due to being used to a case tri stick not john deere controls. I've since done many jobs and now own my own excavator. So it worked out great! First day though, i was in tears because I thought I was going to lose my ass.
