Would a white person look weird visiting a Spanish supermarket?

I've been wanting to visit a Spanish supermarket because I've heard they have all sorts of really good exotic foods and fruits that regular American grocery stores don't carry. I'm a little hesitant though because I'm wondering if I'll get a bunch of strange looks where I am white and all the other shoppers are hispanic. I don't want to look like an idiot. If you've been to a Spanish supermarket, let me know what you've experienced and what people you've seen there.
