引句：
"Through the disloyalty card that is a part of the campaign, every card holder will earn a stamp for every coffee bought at any of the outlets. The card with the completed number of stamps will entitle the card holder to a free coffee at the first cafe they visited." … The campaign is aimed to increase awareness of independent authentic coffee makers in the respective market and to increase targeted footfall in the respective participating cafes.
