Day one of my apprenticeship and the mechanic I was put with (3 ton truck change steering box plus service) took a piece of chalk out of his pocket and marked half a dozen nuts and bolts and said ‘right lad, find the right spanner’s in my box and undo those, put the nuts back on the bolts and remember which ones went where or draw a picture’. 30 years later I was still teaching that basic principle to first years but we had moved on to marker pens ;-).
Nowadays they would probably take a photo on their phone 🤣
