I just met a Fairphoner in my GP’s waiting room. His FP2 was equipped with a (cracked) transparent slim case, so I told him he can get an opaque slim case for free. We didn’t have a long time to chat (an older lady complained I was too loud 
), but he got to tell me of two other Fairphoners amongst friends & family. Of course, I had to tell him of our quarterly Stammtisch meetups in Aachen and our upcoming movie showing.
He was called upon before me, so I’m glad I was shameless enough to push my Fairphone card (just a Fairphone sticker with my name & email address handwritten on its back) on him in time.
