The following are written on scraps of paper, menu's , parking citations, and whatever other bits of paper are lying around. But there appear to be a LOT of them.
My Fellow citizens of Kintargo!
The bridge tolls are an abomination unto the citizenry. From the ivory towered halls of hell I'm sure a silver piece seems like a mere pittance. But to people who actually work for a living that's an entire days wage. The prancing pomps of oldtown feel not only entitled to the good life they live from our sweat, but that we should be so grateful to for their presence to pay for the privilege of working for them.
Demand a pay raise or living quarters for yourself AND your family. When people who have the money start to lose it, they'll complain to the ones in charge. Five minutes with your squalling brats and they'll have perfume scented petitions to thrune on his desk before you can say "but the basement is lovely"
