The current study adopts a variational pragmatic approach to compare the dialogic sequence of the directive speech act of request and its reaction of consent versus refusal in Egyptian and Saudi Arabic. To this end, 413 Egyptian and Saudi undergraduate students completed a Discourse Completion Task (DCT). Data analysis indicated more differences between Egyptian and Saudi Arabic in request consent strategies than refusal strategies. Among the noted differences in consent strategies were Egyptians’ stronger preference for direct strategies and elaborate responses than Saudis who displayed more varied combination patterns and exhibited stronger gender differences. In refusal strategies, however, a general similarity between Egyptians and Saudis was obvious at the level of strategies, combination patterns and the influence of social factors.
