1. Ali gave his doctor's prescription for painkillers to the pharmacist in the pharmacy. Ali then paid $100 for the drugs and was told to return in 30 minutes to pick up the drugs because the pharmacist needed to count the pills and put them in a bottle for Zack.

Almost immediately after Ali left the pharmacy, and before the pharmacist counted the pills, the pharmacy was robbed and all the painkillers in the store were taken by the robber.

Does Ali have to pay an additional $100 in order to have his prescription filled? Was the property in the pills transferred to Zack when he paid for them? Cite any relevant sections of the Sale of Goods Act or Consumer Protection Act.
