Politeness Strategies in Customer Service Interactions at Nigerian Banks in Lagos

Politeness in institutional communication shapes customer satisfaction, brand perception, and the social dynamics of service encounters, making it a productive site for applied linguistic inquiry in corporate Nigeria. This study examines politeness strategies employed by customer service officers in face-to-face interactions at selected bank branches in Lagos, drawing on Brown and Levinson's politeness theory as updated by recent pragmatic scholarship on institutional discourse. Data were collected through non-participant observation of sixty service interactions across three commercial bank branches in Ikeja and Lagos Island, supplemented by structured post-interaction questionnaires administered to thirty customers and ten customer service officers. Interactions were transcribed and coded for positive politeness strategies, negative politeness strategies, and off-record strategies. Findings indicate that positive politeness strategies, particularly expressions of solidarity, appreciation, and inclusive reference, predominate in successful service interactions rated highly by customers. Negative politeness strategies including hedging, indirect requests, and minimization of imposition appear most frequently when officers must communicate delays, declined transactions, or policy constraints. Customers rated interactions featuring a higher ratio of positive to negative strategies as significantly more satisfying, irrespective of whether the substantive service request was fulfilled. The study recommends the integration of politeness strategy training into customer service officer induction programmes at Nigerian commercial banks.
