When I lived in Germany for a while, my phone automatically updated its network to T-Mobile. When visiting France it automatically switches to Bouygues Télécom. When I was staying in Lyon the nearest banks were opposite each other, Crédit Agricole and Caisse d'Epargne. I always went to Caisse. I have drunk Gerolsteiner water whilst living in Germany but that wasn't because of the team.
