I need help getting to my job interview on time, I'm lost!
Do you want to drive, walk, or use public transit?
I want to use public transport.
Unfortunately there are no routes that match your search. Would you like to change any of your criteria?
Yes, I'll go ahead and walk, the job interview is near the Hospital, can you help me get there?
departure location
I don't know, I'm in the middle of the city, I'm lost
Do you see any big landmarks?
Yes, there is the courthouse.
Bus terminal? Anything like that. 
Yes, there is a bus terminal closeby, I'm getting really nervous, I'm going to miss the interview, there are so many people around and none of them will help me.
