Exuse me, is there a police station near here?

Thank you
You are welcome.
Exuse me, how can I get to the university?
Go up the street untill you get to the post office. Then cross the road and turn to the left, go straight on for some time and you will see the university on your right.
Is it far?
Yes, it is quite far away.
Thank you very much.
Don't mention it.
