Similar story:

I was in Medellin, Colombia, outside of the football stadium, trying to see where the rest of our friends were at before heading inside. A guy came up and was saying he was a big fan of one of the teams playing. He lifted his shirt to show me a really shitty tattoo of the team logo. I noticed there was a knife in his wasteband, but I was distracted because I was looking for friends. He asked for me for money and I casually said, “No, Gracias.” and walked away. He started yelling at me with a lot of fun Colombian bad words. I was wondering why he was so mad and as I was walking away, I realized he was trying to threaten me with the knife.

There were a lot of people around and police all around us. Really ballsy on his part for even attempting something like that there.

If I did that in a different situation, I probably would have been stabbed.
