My last Hertz rental had an EZPass but no clunky silver box. The back of the EZPass had the label instruction to close if paying cash, but I could find nothing to close. I carry my own personal EZ Pass and refuse to pay Hertz's PP surcharges, so that meant either wait in the csh lane or avoid tolls. I chose the latter.
If I had slipped a piece of paper in front of the EZ Pass, would that have effectively "closed" it?
