Let us say that he is not a courier as a courier. According to Wikipedia, a courier is a "person who transports important diplomatic or military messages that cannot be entrusted to mail" or "special (and fast) messenger". A person who has a shipment under constant personal control, under his own responsibility, from picking it up to really expressing it for minutes. This is the original meaning of CURIER.
Today this services can offer only small percentage of companies, practically only the citi-couriers. And among them we are a leader in Slovakia since 2007.
