Very sad story. Sorry for him.
Never walk in San Telmo late at night, always give the cell or wallet, do not reach out for the gun, not worth it.
I never like San Telmo, people think it's a cute place, it's very s**ty at night.
I am only comfortable to walk at 3am at the best part of Recoleta and Palermo, and if someone tries to rob me with a gun,
I give everything. I do not carry my passport and important IDs with me. Only little cash and 1 credit card, when I walk
around late at night, I just give it away, no big deal. For the past 10+ years, I walked in Recoleta at crazy hours, when there was no
one on the streets, I have never had any problems.
