Faded ink on restaurant bill

Your faded bill statement reminded me of an instance that happened to me several years ago at La Barra De Potosi. I and a group of friends spent the afternoon there feasting and enjoying life in general including several coco locos. When we decided to leave, we just left. Inadvertently stiffing them on a fairly substantial bill. A year later we again showed up whereupon they brought the previous bill, all wrinkled and faded. They knew I would return and make it right and I had no need to check their math. After 20+ years going to Zihua I can count on one hand the number of times my bill was wrong and most were just honest mistakes.
