Last summer we did a campaign as part of the project 'Busdrivers with character'. The idea of the project was to make passengers notice small but nice moments from their bus ride. The passengers could send the 'moment' by sms or mms to the website www.buschauffor.dk, where busdrivers and everyone else followed passenger experiences on the bus. The busdrivers got a lot of nice messages from their costomers and you can still read them on the website. (Everything in danish though). This is the material we developed to encourage passengers to compliment their driver.
The material was hanging all over the bus, for instance this sticker was hanging on the busdrivers door, to meet the customers when they entered the bus
