What do you think of waiting at bus stops?
What do you do at a bus stop?
What are the bus stops like where you live?
How do you get information about when your bus comes?
Is there anything you feel bus stops are lacking, in terms of comfort, information or whatever you can think of?

Just for the record, I may use some of the replies in a school project (anonymously of course), but don't let that stop you from answering in freeform or just generally relating to the subject rather than answering the questions as they are. Nothing formal.
