Many years ago, when in college, I repaired a broken rung on a chair
for a guy down the hall. Simple deal... some glue, a couple of #4 wood
screws, some putty, and a dab of black paint. maybe 15 minute's work.
As I did the job, he said "Oh, that is the direction you turn the
screws." TRUE story. A friend of my son's does side work changing
light bulbs for people.
