Well....they say we all have Physic power in us, some more then others.
From your story one could assume yours has started to grow, but 1 incident is to little to say anything about.
I know you are a very sensetive man, you knew you did't have any money on you, your worst fear must then be that refusal of the card.
I think you must start to notice if you get more right then wrong when you have such feelings.
Most of us have "such" feelings from time to time, and if nothing arise we just forget about it, but if it happen then we say we knew it.
But again, I said you are sensetive and it's sensetive persons that might have the greatest power
