The girl types some stuff into the computer. The customer snaps her Visa card down on the fake wood altar top; it sounds like a rifle shot. The girl pries the card up using her inch-long fingernails, a dicey and complicated operation that makes Y.T. think of insects climbing out of their egg sacs. Then she performs the sacrament, swiping the card through its electromagnetic slot with a carefully modulated sweep of the arm, as though tearing back a veil, handing over the slip, mumbling that she needs a signature and daytime phone number. She might as well have been speaking Latin, but that's okay, since this customer is familiar with the liturgy and signs and numbers it before the words are fully spoken.
