X: Excuse me! 6.1 Do you know how I can get to the concert hall?
Y: Sure, but it's far away. At least 35 minutes on foot. You have to take a bus or a taxi.
X: Hmmmm.... I guess it'll be a taxi then. 6.2 Do you know or Is there a taxi rank near here?
Y: Well... have you got a phone? It's cheaper to just call a taxi.
X: Sure, I have. 6.3 Can you give me the number?
Y: Of course, I will. It's 889 332 332.
X: Thanks a lot!
