This literally happened in medieval Silesia, where it was so politically fragmented* that the toll colections turned into nightmare and stifled local trade to the point of many interventions from their theoretical suzerains.
*Peak was when the Oświęcim (yeah the same place where Auschwitz camp would later be) duchy which counted something along 3 very small towns and maybe 20 villages got fragmented into three duchies of Oswięcim, Toszek and Zator - but all three were still officially duchies and their rank was theoretically equal to places like Saxony, Normandy or Bavaria.
