I think this is the moral of the story.

Not at all trying to be offensive toward you, but it seems a little naive to go and fetch another card for this person whom you just met. Maybe I'm used to being brought up "in the big city" where my parents taught me to trust NOBODY, but you have to be so so so so so careful around these types. They prey on overly trusting personalities like yours. Think about it: thiefs don't walk around with big signs on them that say, "I'm gonna take your money when you're not expecting it."

Fortunately you were not hurt. And the bank is aware of the situation. But this type of thing was probably a blessful lesson for you--sometimes us humans need to face the worst possible thing in order to prevent it from happening again.

Please, don't let this incident spoil your thoughts of Spain--it's a wonderful country with great people. Que te disfrutes de Sevilla!!
