Curious waiter/ curious customers

At work I always get a lot of my customers asking me where I am from. they tell me I look very mixed... I hear this from many people everyday. its soooooo common for me to hear people tell me I look of mixed race that I'm kind of tired of answering them. LOL! yesterday I took my break from one of my jobs and went to eat at El Torito Grill I only took a couple of bites before I had to go back to work so I asked my waiter to bring me a takeout box so i can take my food with me and eat it later... he came back with a box, a bag, and a question... yes you guessed it! the question was "where are you from?" well again i gave the same answer and again I see a pleasantly surprised face... LOL interesting.
