Go into the pawn shop after you talk to the women. After you talk to the man in the pawn shop, leave. Then, go straight until you get to a sewer drain cover and an object or item toward your left. Pick it up. It will be money. Go back to the pawn shop. Then, walk back out of the pawn shop. Return to the sewer top where you found the money. There will be money there once again. Continue doing this for unlimited money.
