Decided on a trip to the coffee shop again given still heard nothing from boss. Took charity shop coat, despite other half's displeasure at the sight of it, as it was by far the warmest coat I've ever owned. Shop cold as Siberia, so glad I did.
Staff were delightfully friendly, having obviously recognised me from day previous. Asked me how long I had been in this situation, so told them it happened recently after I was made redundant.
Settled down to read the newspapers and having finished one cup of coffee was kindly brought replacement gratis! Must be sure to tell other half about this fine establishment.
