Sam is in a bathroom stall taking a whizz. The stalls lock is broken. All of a sudden while Sam zips his pants up, a guy walks in the stall,closes the door and says..."sshhhh i dont wanna fight...just gimmie your money." Sam says no. Sam is scared and takes a headbutt to the forehead. The guy says "shut up and gimmie da money." Sam then says ok...you want the money and reaches in his pocket and takes his hand out and gives the guy a straight right to the lip. Then another bigger guy pops out of the stall next to Sams, he is standing on the toilet and is an accomplice to the assailant...what should Sam do?
