How do you get to …(practice?)

I came up out of the subway, in a hurry to get to Carnegie Hall for a concert celebrating the construction of the 500,000th Steinway piano. It had been many years since I approached Carnegie by subway, and as I hit the street I was not sure of my bearings. I hustled into the corner bookstore and carefully asked “Where’s Carnegie Hall?”
An amazing series of expressions ran across the clerk’s face. Finally he managed, “That’s not what you’re supposed to say.”
“I didn’t want to give you an easy setup line,” I replied.
“It’s over there,” he gestured, and I hurried on to my concert.
