I am not sure if there were more places with Coca-Cola signs in Marrakech or I noticed the logo more, because it was something overly familiar. Maybe they have Coca-Cola all over London and Paris, too, but it goes unnoticed as it's nothing "strange". But when you're in a city which is in many ways different from what you're used to (let's be honest - when going to Paris it will feel somehow familiar 'cos the landmarks are so famous and known) you notice familiar more? Or maybe, seriously, they just love Coca-Cola A LOT in Morocco.
So yes, always Coca-Cola.
