Here’s a dramatically enhanced version of a true story.
An offshore Malaysian oil and gas asset (which shall forever remain nameless unless someone beats the truth out of me) has had some custody metering problems. They have not been able to prove their liquid turbine meters. So, someone from Operations Technical Support goes out to have a look.
The person steps up to the custody metering flow computers, stares at them, becomes one with them, and tells the platform technicians:
“Cool down the computers.”
It turns out that the control room where the computers are mounted and adjoining electrical room have a defective air conditioning system, something about leaking coolent pipes, and the room has been heating up. The flow computers were heated up enough such that electronic errors in the FCs were causing tolerances to be exceeded.
So portable A/C units were directed towards the FCs. Problem solved.
When you reach this level of CT Zen, then you can be called ‘guru’.

Jabba normally “Zen” connect to custody meter by hitting it with a wrench and hope it is stuck at the min flow before signing a contract.
