Tip : Tipping is not a regular practice in Korea. Service charges are included in your bill for rooms, meals and other services at hotels and upscale restaurants.
Koreans occasionally do tip when they are especially pleased with the service they receive.
Tax : Visitors can receive a refund on a receipt for a minimum purchase of KRW 50,000 (around US$52). To receive this refund, present refund receipts with the purchased goods at the customs desk at the Incheon International Airport when departing. These receipts can be cashed in at the Cash Refund Office in front of the Airport Duty Free Shop.
