What's The Point?

I shall introduce you to 'Mrs Nine Points'. Mrs Nine Points is only one rung lower on the ladder of crazy as Poison Lady, who according to another cashier is infamous not just in OUR store but in the stores her friends work at too! But back to Mrs Nine Points. She comes into the store with a day old receipt asking us to put her missed nine points on her store card cause she forgot it yesterday. I inform her that we no longer do this because people will bring in stacks of late receipts or bring in receipts from their friends who don't have the card. Mrs Nine Points does not take this news well. A fuss is made. Those nine points seemed to be quite vital to her existence. Poor crazy woman, get out of my line.
