Mike, a motor mechanic, owes Helen $5000 due and payable on 24 June 2018. He phones Helen and informs her that he has lost his job and there is no chance he can hope to pay the full debt for a while because there are no job opportunities for mechanics in the area.

Helen says "if you can bring me $1000 on 24 June, and while you're here check my BMW's steering because I'm worried there's something wrong with it, I promise I will not sue you for the rest."
