The show that Rick left for was "Amanda's". He played the chef, Earl Nash, at Amanda's by the Sea - a hotel run by Bea Arthur's character Amanda. The show was based on the iconic British sitcom "Fawlty Towers", but was cancelled after 13 episodes. The show also starred Fred McCarren, who was Neil Bishop in "The Big Heist".
"Fawlty Towers" famously (at least on this side of The Pond) only ran for two seasons of six episodes each (six episodes is the standard season length for British sitcoms), and they were four years apart due to the stars/writers getting divorced in-between.
Here's the first episode of "Amanda's". I assume by the picture quality that it hasn't been released on DVD or repeated lately. Rick appears at just over eight minutes in.
