Do I look Russian?

So, today I was grocery shopping and I got in line to check out. There was this couple in front of me...probably late 50's. The man kept looking at me...I wasn't sure why. Anyway, when I got closer he said something to me in some totally different language...not English or Spanish or Italian or French...nothing that I might recognize. So, after he said something I just said "yeah" because I thought maybe he just had a really thick accent and then he said something else and I realized I had no idea what he was saying. So, I gave him this sheepish look and said "I'm sorry. I don't understand." I was thinking "Is this guy playing a joke?" I totally thought he was going to say "Just kiddin'" but no! He then said in a thick accent in English "I thought you were Russian." Haha!!! I said "No, Sorry!" He then said "what kind of wine are you getting?" So I showed him...it was this new kind I had never tried so I told him "It's new" and then he asked where I got it so I kind of pointed and said "in that area". I didn't want to try to give too many details in case he didn't know a lot of English. Anyway, I guess he must have looked at me for so long because he thought I was Russian! So...do I have Russian-looking features? I don't know but he must have thought so.
