The "counting fare" time thing may have changed recently. I got on the Green Line last week and my normal card had run out of reserve. I got a dollar bill out of my wallet, put it in the machine, and then started digging in my pockets for change. After about 10-15 seconds the conductor waved me away, telling me not to worry about it, and that the machine had already timed out.
