Have you bought a bus pass yet ?   I'm not getting one .   Why is that ?   It's cheaper if I don't buy one .   Buying a bus pass will save you money .   How do you figure that ?   There's no limit to how often you can use your bus pass .   Really ?   Plus , you don't have to use change for the bus anymore .   I like that .   You want to buy one now ?   I'm going to .
