I dunno if rival is the right word, but we all know the 3rd waitresses, Flo, Belle and Jolene were best known for putting Mel in his place. So who do you think was the best at it.

I think it's between Flo and Jolene, but honestly sometimes I think Jolene could be more cutting, Flo seemed to care about Mel deep down.
But practically everything Jolene said was an insult.

Mel and Belle seemed to have an underlying flirtacious thing goiong on IMO.
