Did they think I was spanish?

I went on a holiday with people from around my english community some, and when we were in spain we all were together, even though id rather have been just me and my best friend.well the spanish knew who the english were and they would speak to them in english, and then speak to me in spanish, but even though I was near the group and made contact , I got treated different. I have curly black hair , very light olive skin and green eyes. I mean did thy think I was spanish , but I do speak it quite fluently , but how would they know. also the spanish didnt seem to nice with the english , and they gave dirty looks , but when going in a cafe a handsome man in the doorway stood and let them through and oopen the door themselves, but when I went through he held it open for me. :)
