出国游有许多需要注意的事项。而付小费是很多国家的普遍现象。由于文化习俗的差异，不同的国家、不同的地区做法不尽相同。以下A、B、C、D、E和F是对亚洲一些城市给付小费的介绍，选出符合编号描述的选项。选项中有一项是多余选项。

5.You ae not expected to pay tips at a low class hotel.

A

Bangkok （曼谷） There are no established rules of tipping in Bangkok, capital of Thailand. Some places expect it; others don’t. In general, the more westernized the place is, the more likely you’ll be expected to leave a tip.

   Restaurants: Some expensive restaurants will add a 10% service charge to the bill. If not, waiters will appr eciate your increasing by 10% yourself. However, if you’re eating at a cheap eatery, a ti is not necessary.

   Porters: At Bangkok’s many five-star hotels, you’re expected to tip the porter 20 to 50 baht(铢), depending on how many bags you have.

   Taxis: Taxis are now metered in Bangkok, so there’s no bargaining over your fare. The local custom is to round the fare up to the nearest five baht.

 B

Jakarta （雅加达）  Tipping is not part of the Indonesian culture, but international influences have turned some westernized palms upward in search of a few extra rupiah (卢比).

   Restaurants: A 10% service charge is added at most high-end restaurants. At moderately priced restaurants, 5,000 rupiah should do it---if the service is superb, add an extra 1,000 rupiah or so.

   Porters: Pay a few hundred rupiah for each bag.

   Taxis: Most drivers will automatically round up to the next 500 rupiah. Some will claim they have no change and will bleed you for more. Don’t accept anything more than a 1,000-rupiah increase.

C

Kuala Lumpur （吉隆坡）  Like Indonesia, tipping in Malaysia is only common in the expensive westernized joints, which often add a 10% service charge to your meal or hotel bill.

   Restaurants: If you are at a hotel restaurant, expect a 10% service charge or add the same amount yourself. But at local stalls, there’s no need to add a tip.

   Porters: At five-star hotels, one or two ringgit(林吉特) will be enough. At low-end establishments, you are not forced to tip.

   Taxis: Many taxis are now metered, so you can just round up to the nearest ringgit. In unmetered taxis, expect a session of hard bargaining for the ride.

D

Manila （马尼拉）  Tipping is common in Manila, the Philippines, and anything above 10% will gain you long-lasting loyalty.

   Restaurants: Even if a service charge is included, it is a custom to add another 5%-10% to the bill.

   Porters: Service in top hotels is good and should be rewarded with 20% pesos(比索) per bag.

   Taxis: Most taxis are metered, and rounding up to the next five pesos is a good rule of taking taxis.

E

Seoul   Tipping is not part of the Korean culture, although it has become a rule in international hotels where a 10% service charge is often added.

   Restaurants: If you are at a Korean barbecue (烧烤店), there’s no need to add anything extra. But a luxury Italian restaurant may require a 10% service charge.

   Porters: If you are at a top-end hotel, international standards apply, so expect to tip 500-1,000 won per bag.

   Taxis: Drivers don’t expect a tip, so unless you’re feeling remarkably generous, keep the change for yourself.

F

Singapore City   According to government rules in the Lion City, tipping is a no-no. It’s basically outlawed at Changi Airport and officials encourage tourists to neglect the 10% service charge that many high-end hotels add to the bill.

   Restaurants: Singaporeans tend not to leave tips, especially at the outdoor eateries. Nicer restaurants do sometimes charge a 10% service fee, but there’s no need to supplement that.

   Porters: Hotel staff are the one exception to the no-tipping rule. As a general guide, S$1 would be enough for baggage-lugging service.

   Taxis: Drivers don’t expect tips, but they won’t refuse if you want to round up the fare to the next Singaporean dollar.
