Even before e-tickets became "mandatory" I used to get hassle from a few places who insisted that they take the ticket off to their airport ticketing office to get a paper sticker put on it. Now I fear that they will want to charge me at check-in for revalidating a perfectly valid PAPER ticket coupon.
