I’m purchasing a camera, and the clerk wants to look me up on the company’s computer. Having made purchases at this store before, I give my name, which he enters into the data base, then begins reading off a series of locations, each attached to an ‘Aaron Scott’ who is a customer. None are mine. Finally I offer, ‘Brooklyn,’ and he says, ‘Oh, right, I see you right here: Aaron Scott, Brookline.’ It turns out that I’m not among the twenty-or-so Aaron Scotts in the system, and I must give all of my information again. As I’m leaving the store I remember that the very same thing happened to me the last time I was there.
