Ok...need your help here, this story is unbelievable. 

Apparently three kids were selling candy bars on the corner of Divisidero and Eddy for a school fundraiser when one of them, an EIGHT year old girl, was robbed by a woman trying to come up with $1.50 to buy beer.  The suspect is said to be African-American between 30-40 wearing a black blouse and orange skirt.  SFPD is asking anyone with info to contact them ASAP.  Check out the story and surveillance video from KTVU below:
