Aristocrat Field Service Technician interview questions

The interview was going well until the interviewer asked me why I left a job at an Indian Casino in Arizona. When I told her the tribe was an independent nation and did not pay their half of any Social Security Withholding Taxes. I thought about how this would affect me when I was older and decided to find employment off the reservation. She got very short and terminated the interview. I received an email soon, really soon, afterwards stating I did not meet their "qualifications"?!?! My opinion: Racist Interviewer.
