Mommy Onion saw a supermarket’s full-page advertisement on the newspaper, saying, “The price of XX Cooking Oil is cut down to HK$9.9. Today only.”
After going “yum cha”, Mommy Onion went to the supermarket to buy the XX Cooking Oil at 9:30am. On the way, she found that the supermarket was extremely crowded.
Mommy Onion squeezed through the crowd with great difficulty but the XX Cooking Oil had already out of stock.
Mommy Onion enquired with a staff of the supermarket, “It has run out of stock so early?” The staff replied, “Yes, only one box of oils is available today and they have been all sold out!”
