I visited Spain last month with my family, and while applying for the visa I mentioned I would spend max time in Portugal. I got a Schengen visa from the Portugal embassy. That was the actual plan. I did have a confirmed ticket to Portugal as well.
Then I couldn't go to Portugal and spent the full time in Spain. After I returned, my friends planned a trip to Germany, Portugal and Austria, so I booked my ticket to Frankfurt and out from Vienna. In my itinerary I showed 3 days Germany, 4 days Portugal, and 3 days Vienna, and a confirmed booking from Frankfurt to Portugal.
When I arrived at the embassy, The consul-general went through my documents and started to question me. I was a bit nervous. He asked me about the last time, when I took a visa from here but didn't travel to Portugal. I tried to convince him. But he told me that I was "visa shopping" and told me if I apply for the visa, he will refuse it, and even black list my passport.
I did enter the embassy to submit my passport and documents. I was scared and nervous and left the embassy after a short while. Because I didn't submit my application, would the embassy still black list my passport?
