Abstract
This study is concerned with how native and non-native English use refusal strategy and explored types of refusal strategy within single transactional negotiation. This study was carried out in the diving company office. The sample of this study was 20 respondents in which 10 of whom were from native English speakers' countries such as from England, Australia, and Canada while the other 10 of whom were from Germany, French, Norwegian, Swedish, and Belgium, Switzerland, Spain, and Finlandia. The data were gathered through observation using an audio recording device. The data were analyzed through conversation analysis and refusal mapping technique. The result of the study showed that the refusal expression occurred in the last exchange of negotiation and that both respondents (Native and non-native English speakers) used the same strategy to refuse the offer made by the receptionist i.e., "Postponement with General acceptance with excuses". About 70 percent of native speakers used this strategy while 80 percent of nonnative English speakers used this strategy and the rest used pure postponement with alternative reason. Besides, it also showed that most of the strategies used by both speakers were categorized into commissive speech acts that are the promise of future acceptance.
