Price per hour is immaterial if the workshop:
1/. is not managed competently
2/. covers up every mistake
3/. passes off sub-standard work as competent
4/. will not follow their own systems and as a consequence makes major ****ups like pulling the wrong engine and bulk-stripping it.
I have found very few workshops and Chief engineers that are trustworthy and that consider themselves partners in our business (as opposed to simply the beneficiary of a blank cheque every 100 hours)
The biggest fcukup can be fixed but it doesn't take much of a cover-up to ruin everything.
