I need to buy a bus pass .   What kind of bus pass would you like to buy ?   What are the different kinds ?   You can get a day , weekly , monthly , or student pass .   Could I get a student pass , please ?   Sure , can I see your student ID ?   Sure , here it is .   Very good .   How much for the pass ?   It's free , but the monthly sticker is $ 24 .   Okay , I'll take it .   Thank you for your purchase .
