The problem I had was the over the top nature that they gave it. Like, we wouldn't recognise it as a small town diner, because as an audiance (according to Lucas) we are idiots and have to be spoon fed everything.
The whole "Someone to see you hon'! You wanna cup a Jawa juice?" Who the hell talks like that, ssspecially in a Star Wars universe? I mean, they actually programmed the droid to sound and act like that? That is a very distinct accent. On a human I can understand, but a droid. Oh no, I don't buy it.
Dex was fine. He looked and acted like he was a truck stop short order cook. Even the whole "itching his butt with his available hand" was okay. I smerked to myself in the theater. And as a side note, Obi-Wan did have the droids look at the dart but as Dex said, "even a Jedi should know the difference between knowledge and wisedom."
I just hate that damn droid. She is what makes it a slap in the face from George Lucas.
