She was ringing me up and said to the woman next to her "칠삼구 (chir-sam-goo)" which translates to "seven-three-nine" (incidently, my lunch came to $7.39). So, now that things are finally becoming clear for me...I can't have my tutor move back to South Korea.
And yes, I am taking Korean and the "why" is a funny story. So, last year I was going to Japan for vacation. I tried to learn Japanese by finding a Japanese tutor. But, all my Japanese tutors would flake after setting up the appointment. So, randomly, I got an email from my current Korean tutor saying that he couldn't teach me Japanese but he could teach me either Chinese or Korean; my choice. After meeting him I found out that he was from South Korea but had lived in China for three years. Well, his Korean was clearly better than his Chinese (by his own admission) and I opted to learn Korean instead.
So, that's the whole sordid story...lol...but I'm still bummed because I have no real desire to post another ad on CL and sift through a series of odd emails to find that needle in the haystack again. :-/
