Based on her response. I don't think you will get the job. I've had people treat me like that during job interviews. One guy even gave me the runaround making me come back and wasting my time just because he couldn't say no. Though that job looking back wasn't worth it anyway. I found a much better one with people that valued me and made good money. So if you lose the opportunity, even if you stutter, there are better opportunities I promise. Focus on jobs where you work with your hands.
