As you mentioned in another thread, it really depends on the person and their mood!
I got an online turno for AFIP, arrived a bit early with the documents. While they were reviewing them, they wanted to see my Certificado de Domicilio, they did not like it and asked me to go to the police station and get another one addressed to "AFIP" (mine was for Migraciones) and bring them the original.
Then while I was making some extra copies they asked for, this employee went on a lunch break. So at my original appointment time, they called me over again and this time someone else helped me and I got my CDI on the spot.
- Meanwhile, they also had a disagreement with someone else there on whether the code should be issued with my precaria or passport. Afterall they didn't even check my passport or get a copy of it, which the first employee had asked for.
Just wanted to share, whether your life can be made suddenly so difficult or not really depends on your luck!
Thanks again for the information though.
