Amos Lydecker is one of Jimmy McGill's elderly clients.
After hearing Jimmy talk to Alma May Urbano about being overcharged by Sandpiper and having her money taken, Amos questions Jimmy about it. Jimmy explains that Sandpiper may have overcharged them, too, and offers to help get their money back. Shortly thereafter, the seniors file off the bus at their restaurant destination, handing a pleased Jimmy their signed letters of engagement. ("Amarillo")
