Good to hear that you managed @danilamarilu
I am also traveling with very little of money, so I spent most of my travels, volunteering in different places in exchange for a food and stay. That is totally fine in my eyes! If you can make a deal which is beneficial to everyone, it is perfect.
However, I don't like when people expect things in exchange for nothing. I met so many people like that. I totally agree with you - as long as we are living in this world and staying in a human's body, we have to follow some rules. Even Gods in a human body have to eat something not to die. Going against those rules is not rebel, but more silly.
