and I refused to accept those candies.

I kept leaving the store with .50 dirhams change unclaimed. That lasted for a week. The next week, I went in to buy PEPSI & water...and I went straight to the door. The storekeeper stopped me and ssaid I didn't paid for it....so I told him: "YOU HAVEN'T RETURNED MY CHANGE which is QAR2.50 riyals...and the PEPSI AND WATER costs the same, WE'RE QUITS.

He scratched his head and let me go. From then on, they always have change/coins for me ;P
