Diamond in the Rough is one of my personal favourite episodes on the Golden Girls. Plenty of laughs and a wonderful story.
Jake a former navy cook operates a catering company called VIP Catering. Blanche instantly falls for him. Both of them hit it off. However, Blanche begins to see that his "etiquette" standards are mediocre at best. Blanche really looks down on Jake because her standards always must be at a high level. Blanche can be so self-centered. Don't get me wrong, I love the character of Blanche Devereaux but here in this episode she lets him slip through her fingers and that he is a wonderful man with a heart of gold even though he has a bit of a rough personality. Jake breaks up with her. Later on, Blanche is upset and realized he missed another opportunity in choosing a wonderful soul mate.
