An important GSF innovation in Lyon-Saint Exupéry airport: customer satisfaction terminals installed in the airport toilets. Users are asked to express their opinion on the hygiene and cleanliness of these very important spaces. We have a unique traceability tool that is very useful for our customers and for our teams. The results can be checked via an app and on our a dedicated website. As well as our own image, we believe that these terminals serve the brand image of our customer.
