It's a shame they lost you as a customer over $1.50 . I think you should call and tell them, now that the shock has worn off, because it might be an eye-opener. Why would they simply not allow partially-filled cards to be redeemed? Or say we don't combine cards (ie you can't have 8 punches on this plus 2 on that to give you your 10th punch). Not that I see anything wrong with that, but maybe they've had cheaters or people holding up the line digging for their card. I don't know, but if I were the owner, I would want your feedback because I would guess this policy rubs a lot of people the wrong way. I certainly would not pay $1.50 for a card. Nor would I be careless with one if the reward were worthwhile.
