I am the customer now for a bit and do my best to be nice to contractors. When I worked as field service engineer though I absolutely despised a certain offshore drilling company because they always had the thickest possible people in their crews and chose the cheapest possible always with little thought for value.
An interesting one they had was a thing for GE, everything had to be GE... so on new built ships their GE propulsion drives couldn't get the ship to design speed without tripping, their ballast control system designed by GE nearly toppled the ship (no return point was 12 degrees, they were oscillating the ship side to side peaking at 11), their drilling VFDs couldn't do what pretty much all other vendors did and to top it all off in some instances they were just snapping off motor shafts because of drives fighting each other. Somehow they always went for them.
No usable internet for anyone onboard, no communication between any of the hierarchy levels and strictly no niceties at all... like sticking two guys in the same room at an empty hotel.
The funniest was their lack of knowledge of physics... they wanted this winch to be very fast but had no weight on it, so it couldn't be very fast because it needs space for stopping within the confines of the derrick. Still in business though... they're pretty much the only ones with yellow coveralls.
