Damn I'm sorry to hear that, unfortunately crime is low but it's still there, especially in the bigger cities when it comes to stealing things. I hope you aren't agitated anymore and managed to sleep at least a little 😢
I remember that when I was in Rome a guy tried to steal the phone from my dad's pocket since it was sticking out from the back of the trousers, in broad daylight, in the middle of the street and with no people around, as if it was the most normal thing in the world. Luckily he changed his mind and kept walking in another direction as if nothing happened (I saw it from distance but was ready to pursue him in case)
