A: I need a taxi.
B: We could easily provide you with a private vehicle, if you'd prefer.
A: No, the taxi will do.
B: Perhaps you'd like to take a beautiful limousine.
A: No, thank you. Taxis and I get along just fine.
B: No private vehicle, no limo. Got it. Where are you going?
A: I'm seeing a show at Rockefeller Center.
B: What time should the taxi be here to pick you up?
A: I'm ready to go right now.
B: I'll have a taxi for you momentarily, sir.
A: Great! As soon as I brush my teeth, I'll be downstairs.
B: You'll enjoy our new, clean taxis, sir.
