question:
Article: When I worked as a waitress in Chicago, US, my coworkers and I would sigh whenever we heard someone with a foreign accent coming into our restaurant. We knew what it meant to serve a non-American: no tip. We would work just as hard as we always did, but we might not get paid. Americans have an unspoken rule about tipping: they give tips to almost everyone who offers them a service of some kind. Americans tip their waiters, barbers and taxi drivers. An appropriate tip is between 15 and 20 percent of the amount charged for the service (But the charge for the tip doesn't appear on the bill. The customer is expected to add it himself/herself.) Tipping less than this sends a message to your waiters that you think they've done a bad job serving you. And to leave no tip at all is simply unacceptable. It's not that American waiters are greedy. In many countries, waiters are paid a salary for their work. They'll earn money even if no one comes into the restaurant. This system offers much more safety for waiters than the American version. In the US, waiters know that a night without customers means a night without pay. Some countries include a tip for waiters - a "service charge" - on the bill itself. Since the tip is included with the other charges, waiters don't need to worry about people forgetting to tip. But in the US, waiters do not receive a salary, and service charges only appear on bills when there are six or more customers at the table. Since almost all American customers are familiar with the system, they know to add a tip without being told. But visitors to the US may expect waiters to be paid a salary, or think that the tip is included on the bill. So much as we waiters loved hearing stories about other places from our foreign customers, we were always nervous when they got ready to leave the restaurant. We were never sure what to expect.

question:
Article: A cute invention was revealed this month at the International Robot Exhibition (IREX) in Tokyo. It's called Jukusui-Kun ("deep sleep" in Japanese) ---a robotic pillow in the shape of a polar bear. The pillow is in fact a serious technological innovation hidden under a cute cover. It was developed by a group of scientists and engineers at Tokyo's Waseda University to help people suffering from snoring   and those who live with them. This is how the robotic pillow works: a microphone detects the noise level of the snoring, and if the snoring becomes very loud, which can be the sign of sleep apnea  , the bear will raise its hand and carefully touch the face of the sleeper, leading to a change in the sleeper's position without waking him or her up. This is definitely the world's first anti-snoring machine and an important potential treatment for sleep apnea. This sleeping disorder involves pauses in breathing, and can lead to heart attacks during sleep. In Japan, around 2 million people are struggling with the problem. When a sleeper starts snoring, the sleeper's blood oxygen level drops. The new device tracks   the level of oxygen in the sleeper's blood and wirelessly sends the information to the polar bear. But the only problem is that people not only have to sleep on a bear-shaped pillow with robotic hands, but also have to insert  their hands into a monitor that keeps track of blood oxygen levels. If these levels fall below a certain point, it gives the bear another cue   to lift its hand. The bear is not yet on sale, and it remains to be seen whether a robotic hand reaching up to touch one's face is any more effective than one's partner giving one a good shove  . 
 Answer: With this device, the sleeper's hands can't move freely while sleeping.
