The trouble is that we northern Europeans tend to be open, friendly and generous and therefore seen as a soft target. After being robbed twice, I was followed into a cafe by a beggar to whom I had already refused money. He stood over us at the table and refused to go until he was given some money. I refused to give him anything and the cafe owner eventually came over and helped get him off the premises. Then a group of four holidaymakers (I think they were Dutch or Scandinavian) sitting at the next table turned on me and accused me of being mean in refusing to give him a few euros!
