Texas Roadhouse interview questions

I applied on a Thursday, received a call on Saturday, met with the manager Sunday, started training on Tuesday. None of the questions were trick questions. Mostly about my background, my availability, and what characteristics I'd like a server to have if they were waiting on me.

In 10 years, this was single-handedly the most unprofessional interview I had ever been a part of, after driving an hour to meet with the Marketing Partner (who was 15 minutes late). This was for the NC market. Some incidents during the interview: -"How old are you? You look like a baby." -"Where are you from?" "I recently relocated from *****" "NO, where are you FROM? Like, what's your origin?" (I am non-Caucasian) Then when I told him, he stated, "Well, I don't have one of THOSE on my team! That should be interesting!" -"You know, you wouldn't even be here right now if I didn't know someone that you used to work with." -"I actually don't need a General Manager for any of my stores - why should I hire you?" -Being debated with that my previous salary must be false; although I provided my previous supervisor's information as a reference on my resume and reassure that he could verify. -"I whip my team into making me the most money possible - can you handle that?" -Taking a personal call during the interview and using abrasive language and cursing. -Told I was "uptight" and that I "couldn't take a joke" and needed to "loosen up". ...I was still offered a position, 3 days later. I politely declined.
