For whatever reason, my brain always goes to a "copy my homework" mentality.
Even as young as 7th grade, I was annoyed by people who wanted to copy my homework. Now, if you wanted to PAY me to copy my homework, that's different altogether. I spent the time overnight to do the work, why shouldn't I benefit??
But the "homework" also applies to researching the job and/or simply knowing how to complete it from experience.
The homework is sourcing parts and ordering them.
The homework is putting together a nice space where you can readily lift a vehicle overhead, compress coil springs, press out a u-joint, press on a wheel bearing, file caliper slides, pull on drum brake springs, easily remove a transmission on your feet with one person etc etc
Wanna copy my homework? You gotta pay. Or do ALL the above yourself -- it's a free country.
