    A few days ago, Adrian bought six packages of ink for his printer at a $1 Store. Then he found a deal on better ink at the local computer store. So Adrian went back to the $1 Store to exchange the ink for some other items.

    He put the ink into a plastic bag and tied it up. When he entered the store, he immediately showed the bag to a clerk and told her that he was returning some items. She looked at him but said nothing, so Adrian put the bag into a push-cart and started shopping.

    He was midway through shopping when a female employee suddenly stopped him. “Sir,” she said sternly(严厉地), “you are not allowed to carry a plastic bag of items around in this store.”

    Adrian was taken back. There was no need for her to yell. He opened the bag and showed her the six packages of ink. “I’m exchanging these for some other items,” Adrian said.

    “You should have left the bag with the clerk when you entered the store. Let me see your receipt!” the employee demanded. Adrian was embarrassed. He felt like a shoplifter while he showed her the receipt.

By the time Adrian had finished shopping and exchanged the items, he was angry and asked what her name was. She mumbled something and he heard “Ursula.”

    When Adrian got home, he called the store’s corporate headquarters. Two days later, Adrian received a phone call from a representative. “I’m sorry,” she said, “but there’s no one at that store named Ursula. Can you describe her? I’ll find out who she is. I assure you, we do not tolerate rude behavior, nor do we tolerate lying to customers.”

    By this time, Adrian had calmed down. He didn’t really want the employee to lose her job. He told the representative to forget about it.

Have you dreamed of building your own machine? Do you wish you could invent something new? Here we look at a few British inventions of recent times.

Adaptive glasses

Do you wear glasses? If so，can you imagine life without them? In 1985，Joshua Silver，a professor at Oxford University，asked himself，“Can I invent a pair of glasses that could be changed by the wearer？”He designed two plastic lenses(透镜) that are filled with a special liquid.Using syringes(注射器) you change the liquid between the lenses until you can see clearly.The glasses are not beautiful but they are easy to use and cheap to make.

The wind­up radio

When you switch your TV on tonight，think about all those people without electricity.Thinking about this，Trevor Baylis came up with the idea of designing a radio that could be powered by hand.In common with Joshua Silver he wanted his invention to be cheap and easy to use.He wanted even the poorest people in developing countries，who don't have electricity and cannot afford batteries，to use it.The radio has a generator(发电机) which is powered by turning a handle.In 1996 it won the BBC Design Award for Best Product and Best Design.

The Dyson vacuum(真空) cleaner

In many homes around the world you can see a cleaner that looks like a spaceship.This is the Dyson vacuum cleaner which uses something called “cyclonic，separation” to separate the dirt.You do not need a bag for your cleaner and it does not get blocked so it is very practical.The idea came to Sir James Dyson after he kept having problems with his vacuum cleaner.He decided he could design a better one and in 1993 he opened his own factory.The Dyson is now one of the bestselling cleaners in the UK and Dyson is believed to have earned over a billion pounds.

The Zapata Flyboard

Have you ever dreamed of zooming through the water and leaping in the air like a dolphin? Now you can thanks to a flyboard，built by water sports enthusiast Frank Zapata.With it you can dive back in the water and out again.It's possible to jump to incredible heights out of the water—over 30 feet.The basic flyboard model comes in at ￡4，200.

So keep dreaming and inventing.One day you might get it right.
