That sucks. $120 isn't that bad, I fronted some dude $700, and he claimed to have gotten robbed. I had to "peacefully" extort him to get it back, because I figured his story was bullshit. I don't know I would try to confront him, not in any violent matter or anything, and demand it. If worse come to worse, have a bic and clench it in a fist. Adds a little umf to your punch.
