Clinching The Bolt

It needed just an extra turn to make the bolt secure,
A few more minutes on the job and then the work was sure;
But he begrudged the extra turn, and when the task was through,
The man was back for more repairs in just a day or two.
Two men there are in every place, and one is only fair,
The other gives the extra turn to every bolt that's there;
One man is slip-shod in his work and eager to be quit,
The other never leaves a task until he's sure of it.
The difference 'twixt good and bad is not so very much,
A few more minutes at the task, an extra turn or touch,
A final test that all is right-and yet the men are few
Who seem to think it worth their while these extra things to do.
The poor man knows as well as does the good man how to work,
But one takes pride in every task, the other likes to shirk;
With just as little as he can, one seeks his pay to earn,
The good man always gives the bolt that clinching, extra turn.
