Strange story parabellum.
The vast majority of my engineering experiences are good, but the very occasional bad ones are the total opposite to your posting.
There's so much OTP pressure in CX, that engineers are trying to short cut things to achieve OTP.
Tight turn around where there's a defect raised by the previous crew, or alternatively, a clean aircraft has a problem occur during the preflight, or even during pax boarding. Call the engineer: "please fix". As he looks at his watch and says "but it will take a long time".
I'm not kidding. I've seen it happen more than once.
Safety is our priority.
Maybe it is a priority, but OTP has a higher priority.
