mistaken identity

I was walking through a local mall. While I was walking around the dead sea cosmetics sales girl approached me and tried to woo me into buying their products. I initially didn't notice that she works for the dead sea cosmetics and just tried to ignore her. She asked me whether I know about their products. I initially told her no, but after noticing that it's the dead sea cosmetics I told her that I'm originally from Israel and started talking in Hebrew to her. She was stunned and kept saying that she didn't believe I was Israeli and that she always distinguishes between Israelis to non Israelis and that I didn't look like Israeli at all ... I found the whole situation very amusing :-)
