Season 6 Tennille
Tennille made it way too far... It was clear she was not very knowledgeable and out of her depth. All the other chefs did not respect her and knew she was out of her league. I think Tennille mostly had easy stations and was able to skate on by. By the end she had burnt all those pans just cooking fish? She was in the final four and could not cook fish or scallops? Wow... And Gordon eliminated her on the spot. That's pretty bad.
Someone like Suzanne, sure she was not very likeable and came off as pretentious and a know-it-all but at least Suzanne clearly was highly skilled and knowledgeable. She just lacked social skills that's all. Tennille seemed incompetent
