[Macdaddy Warsaw]

I'm not doing anything for the guy getting robbed by more than 1 guy, but if it was one guy (even with a knife), I'd look for that weapon and bash him (in a sucker punch way), or I'd just act like I was walking past and lay on a good suckerpunch assuming I believed I could hurt him enough where he wouldn't be able to retaliate.

Hell, if I actually stopped being rational about it, I might try to take on the bigger group. I'm a little bit of an idealist romantic...
