11.5 hour work day just ending, and almost nothing to show for it. Went to $customer office to set up printers. Discovered that they had purchased a print server device that was incompatible with the printers that they had purchased, even though both units were from a certain unnamed large printer manufacturer located in LEXington Kentucky. Felt like a complete incompetent by the end of it all. I'm not sure I care for being sent on these fool's erands for which I am completely unprepared. It's embarassing, depressing, and expensive. However, I did hit a geocache on the way home, so the day wasn't a complete loss.
