Stop in for a cup of coffee

Long before i was a certified mechanic, this being one example i used. I said to my employer " if this is what a certified mechanic is, i dont want to be one"
There were two ticketed guys i worked with,i learned from their mistakes. My comeback rate is near zero.
The ford dealer i worked at was struggling,big general meeting and mangement wanted to know why comebacks were near 50%.
I was a service writer,and witnessed the **** work.one tech was busting his *** fixing all the screw ups,where he should have been a lead tech and could oversee the work and nip problems in the bud. He left and so did i.
Sounds like the 2 screw-ups were tight with the management. And you were the rain on their parade.
