Interdimensional Traveler

You sneak out successfully. You run away from the warehouses, unseen by anybody, and hail a cab as soon as you get out to the street.

"Where to?" says the cabbie?

"To the Presidential Headquarters." you say.

Twenty minutes later, you are at the Presidential Headquarters. You walk in and tell the secretary you desperately need to talk with the President.

"Do you have an appointment?" she asks?
