B&N isn't the only one to do this but they are one of the most persistant. I visit the store once or twice a month and have been since Borders tanked. Every time I buy something, I get this spiel. Dozens of times now. Usually, I cut them off with a curt "no" when I sense they're ready to start the question. I sort of feel bad because it isn't the clerks fault but I'm really annoyed at just being asked over and over. I'm tempted to have a badge made up I can pin to my shirt that says "Thank you. No.".
