Once a friend asked me to buy him cigarettes while I went into the store to buy some food for myself and he was waiting outside. I did it, but I hated every single second of it. The fact that the cashier, and anyone around me could potentially think I was a smoker... utterly terrifying. The humiliation was even greater when the cashier asked for my ID (I was around 20 that time, I looked young enough for them to assume I was underage). Disgusting, horrible experience. Never again.

There was another case, where my best friend actually didn't really ask for help, but it was a really serious case. Her mom got into jail as a victim of someone else's attempt to clear himself in a corruption case. I helped her with my savings (a thousand dollars or so) to get her out of jail. Well, this was another horrible experience, but in a different way. I would do it again if such a situation arises, but luckily her and her entire family have managed to move to a better country since then.
