Excuse me? Yes?

Could you tell me how I can get to Church Street? I'm sorry. I don't know. Is it near here?

I think it is. It's in London, W.8.
London W. 8.? That's Kensington. It's a long way from here!

How can I get there?
You'll have to get a bus. Get a number 73.

Where does the number 73 bus stop?
It stops over there. Ask the conductor for Kensington High Street.

And how can I get to Church Street from Kensington High Street? I don't know. You'll have to ask someone when you get off the bus.
