Stop in for a cup of coffee

How about this. My wife works for the state, she is nearing retirement, BUT she has been working from home since the Kung flu hit. She takes a toll road to work, saves about 45 minutes each way. But the toll road is free if you are a car pool. Two or more. So, I figured out, when she has to go back to her office, it is less money if I drive her to work and pick her up, because of the savings on the toll road!! Crazy!!
