I was served weak ass coffee WITH sugar already in it once
Joking aside, I assume your friend is trying for asylum. So it would have to be something real and documented. I've been mugged multiple times growing up, beaten a couple of times, my combi's windows smashed all around me by an angry mob bent on destruction (and they were from construccion civil), but all that means nothing to a judge. It's just part and parcel of growing up in a third world country. If your friend and his or her family was a specific target of violence or political, religious or racial discrimination, then that might be a good case. And they will ask if there's at least a police report, preferably a newspaper article too. Anything fabricated or unsubstantiated would put his application in risk of being denied
Best of lucks to your friend though!
