Towards a Declination Slot

Conversation analysis of 1,180 excess-reduction offers at the vehicle-hire counter, and the audited pause adopted from it

A research poster from the School of Continuous Improvement treats the excess-reduction offer made at a vehicle-hire counter as a sequence, transcribing 41,208 conversational turns from 1,180 recorded pick-up encounters at 24 depots across four operators. Acceptance is accomplished without speech in 62 per cent of offers and launches a median 0.20 s after the offer's completion; a plain refusal launches a median 0.94 s later, carries an account in almost every case, and draws at least one further offer in 84 per cent of sequences, with no depot in the sample producing an unmarked refusal turn. The poster attributes the asymmetry to the script rather than to counter staff, and recommends a two-second declination pause held before any pursuit turn and audited from the counter's own audio.
