So I don't think she did it to spite me, but I feel like she pushed harder and tried to make a greater impression(in terms of interviewing) at that location compared to others. Of course, that's speculation.
WILD speculation. They knew her, they liked her work, her work ethic, she matched.
I guess you're at an impasse that the courts will need to sort out.
It just so happens that that Spartanburg location is close to her parents, sister and brother (they live less than 2-hours away in TN).
