Look at all the buses now that want exact change, exact change. I figure if I give them exact change, they should take me exactly where I want to go.

Meaning of the quote

This quote is about how some bus drivers now require passengers to pay the exact fare, not more or less. The speaker, George C. Wallace, believes that if he gives the bus driver the exact change the bus driver asks for, then the bus should take him exactly where he wants to go. He thinks the bus driver should provide the service he expects since he is paying the right amount.
