This, I was abused as an apprentice 8 odd years ago and told them to keep the job, I like to respect them as if you give them shit then they lose interest, only thing I have done to an apprentice was stuck a fire hose in the toilet window, mind you this was during after work drinks after he got under the weather from one GOLD so I did it as a shit stir and nothing to do with the job.
I was also a parts guy at this time so him and I got along well.
