     In recent years, Israeli consumers have grown more demanding as they've become wealthier and more

worldly-wise. Foreign travel is a national passion; this summer alone, one in 10 citizens will go abroad.

Exposed to higher standards of service elsewhere, Israelis are returning home expecting the same. American

firms have also begun arriving in large numbers. Chains such as KFC, McDonald's and Pizza Hut are setting

a new standard of customer service, using strict employee training and constant monitoring to ensure the

friendliness of frontline staff. Even the American habit of telling departing customers to "Have a nice day"

has caught on. "Let's be nicer", says Itsik Cohen, director of a consulting firm. "Nothing happens without

competition."

     Privatization, or the threat of it, is a motivation as well. Monopolies that until recently have been free to

take their customers for granted now fear what Michael Perry, a marketing professor, calls "the revengeful

consumer". When the government opened up com- petition with Bezaq, the phone company, its international

branch lost 40% of its market share, even while offering competitive rates. Says Perry, "People wanted

revenge for all the years of bad service." The electric company, whose monopoly may be short-lived, has

suddenly stopped requiring users to wait half a day for a repairman. Now, appointments are scheduled to the

half hour. The graceless EIAI Airlines, which is already at auction, has retrained its employees to emphasize

service and is boasting about the results in an ad campaign with the slogan, "you can feel the change in the air."

For the first time, praise outnumbers complaints on customer survey sheets.

1. It may be inferred from the passage that _____.

A. customer service in Israel is now improving

B. wealthy Israeli customers are hard to please

C. the tourist industry has brought chain stores to Israel

D. Israeli customers prefer foreign produce to domestic ones

2. In the author's views, higher service standards are impossible in Israel _____.

A. if customer complaints go unnoticed by the management

B. unless foreign companies are introduced in greater numbers

C. if there's no competition among companies

D. without strict routine training of employees

3. If someone in Israel today needs a repairman in case of a power failure, _____.

A. they can have it fixed in no time

B. it's no longer necessary to make an appointment

C. the appointment takes only half a day to make

D. they only have to wait half an hour at most

4. The example of E1Al Airlines shows that _____.

A. revengeful customers are a threat to the monopoly of enterprises

B. an ad campaign is a way out for enterprises in financial difficulty

C. a good slogan has great potential for improvement service

D. staff retraining is essential for better service
