About 13 years ago I read this short story in a book of sci-fi short stories.  It was told from the perspective of someone who is talking to a person in a room.  The person cannot see the narrator.  The only other details of this story I can recall are: 

1. The narrator tells the person that certain things no longer exist such as the World Trade Center (pre 9/11) and the letter Q, and that things seem kind of "kweer". 

2. The narrator offers the person a girl, but says that she is not being offered as a "bribe" saying--and I'm paraphrasing--"the powers that be know you well enough not to offer you a piece of ass to get your attention".

Any help would be greatly appreciated.
