Effective communication between people from different cultures requires not only the ability to speak a common language but also an awareness of sociocultural rules and sociolinguistics features, an important one being speech acts the realization of which realization by Emirati non-native speakers of English has not been studied sufficiently. This paper investigates a particularly face-threatening speech act - refusals. It explores Emiratis’ comfort level and the use of the refusal speech act in communicative exchanges with unknown tourists. The data set consisted of 94 participant responses to a pre-instructional activity in an introductory linguistics class. Both descriptive and inferential statistics were used to analyze the data sets. The key findings suggest that both male and female participants were rather comfortable conversing with a tourist couple that they had never met, but male participants reported being more at ease accepting the couple’s request to take a photo with the tourists at a statistically significant level. While more than half of the participants reported willingness to take the photo with the tourists, approximately 41.5% would decline such a request, with significantly more females declining the request. The most frequent components of the refusal speech act included a statement of regret, a thank-you note, and an excuse, reason, or explanation. Results also showed that linguistic devices for positive politeness purposes were used rather sparingly, and it was mainly the females who used them. Based on the results, it is helpful for visitors to the UAE to be mindful of Emiratis' sociocultural and sociolinguistic behaviors so that the nuances of communication can be understood and responses are appropriate, which can reduce the likelihood of communication breakdowns and increase the well-being of all involved in the interaction.
