00:00This supermarket installed a special revolving door. Once it closes, it locks completely.
00:04There's only one way out. Push the door in circles to charge it. The door opens automatically when
00:09fully charged. The first customer Lena walked in. She couldn't get the door open no matter
00:13how hard she tried. An announcement came over the speaker. This is a human-powered eco door.
00:17You must keep spinning it to charge it up. Lena understood and started pushing hard.
00:21It was very difficult at first, but it got easier as she kept going. The door was fully
00:25charged quickly. It burst open suddenly. Lena got flung into the store. Even employees had to
00:30charge the door to get to work. Manager John was thrilled with this door. He believed the store
00:34would go bankrupt soon. The revolving door attracted many fitness enthusiasts instead.
00:39TV news crews came to cover it. People made special trips just to work out there. The news said this
00:43store offered shopping and fitness together. More and more customers came because of the publicity.
00:47The store became hugely popular again. The owner thought this was John's marketing genius.
00:52John was suffering in silence. The company CEO heard about it and came to inspect. He charged the
00:56door to get in and was charged 100 Korean one-entry fee. Staff gave him a box of ginseng as
01:01well.
01:01He discovered customers had to kneel to process returns. CEO Jason had never seen such strange
01:06business practices, but profits were all that mattered. He confidently left the store in John's
01:10hands. John met an entrepreneur on the street one day. The man had packaged his family cold noodle
01:15jelly into boxes, but the shelf life was extremely short. Other stores refused to sell it.
01:19John was thrilled when he heard this. He loved products that didn't fit the mainstream market.
01:24John didn't negotiate the price down. He signed a supply deal at triple the market price.
01:28This made it more expensive than beef. With only one day shelf life, unsold products would be thrown
01:32away. John even signed a 10-year contract. He thought this would help the supplier profit while
01:37making the store lose money. He had no idea how delicious the jelly actually was. One bite tasted
01:42absolutely incredible. This jelly recipe was passed down from his great-grandfather. It was once made
01:46exclusively for the royal court. Even the emperor was amazed when he first tried it. The jelly sold
01:51out within minutes. This delicacy quickly became a nationwide sensation. Even foreigners made special
01:56trips to buy it. The supplier wanted to repay John's kindness. He promised to sell exclusively at
02:00this store only. It would never be sold through any other channels, as the jelly became wildly popular,
02:05and it wasn't available elsewhere or online. Many foreign tourists made special trips to buy it.
02:10This store even received a personal commendation from the president. Others try to make money but can't.
02:14John tries to lose money but can't either.
