Mulla went to the public bathhouse, but the attendants ignored him and gave him terrible service. Despite this, on his way out, Mulla tipped them ten gold coins. The attendants were absolutely shocked and thrilled by his generosity. The following week, Mulla returned. Remembering the massive tip, the attendants treated him like royalty, scrubbing him, massaging him, and bringing him tea. On his way out, Mulla handed them a single copper penny. Furious, they asked, "What is this?! After the incredible service we just gave you?" Mulla smiled. "This penny is the tip for today's service. The ten gold coins I gave you last week were the tip for today's service."
