This document provides instructions for staff to systematically collect customer contact information for a customer satisfaction survey in an unbiased way. Staff should ask the first customer who approaches the reception desk at the beginning of each hour for their contact details and if they decline, ask the next customer. They should continue this routine each hour to collect at least one contact per hour. The goal is to gather a broad range of customer perspectives by collecting at least 10 addresses per day without selectively choosing particular customers.
