I wrote before, more than once, about my experiences at the Olde Tyme Gaslight Restaurant in Fayetteville, New York. I was a 17-year-old stoner who worked as a dishwasher there, but what went on didn't escape my attention. One night someone knocked on the back door - it was the meat delivery guy. I told him to put it in the walk-in and he said, "Not so fast! Nothing comes off the truck until I get paid in cash!" Seems we had stiffed the meat company and they weren't giving any more credit. The dinner rush was set to start and the cook (who was also a part owner) scrambled to come up with the money.
