I inadvertently jumped on a section of Raleigh toll road. I was concerned about where to pay the toll. The mail you a bill
The bill was for $0.41, the postage was $0.43
Now actually that’s not right. They got you where they want you. Ooops, didn’t know this was toll? Well, here’s your bill! Hiding it effectively so people don’t know they’ll be paying. Hence why toll booths are a good thing.
