We need a new Ice Age . <| sep |> Your analogy of the big mac is incorrect . What would be a more correct analogy is if someone used money to say , buy a voucher for a big mac that you can use anytime . However , the next week they suddenly say that vouchers bought that week can get double the rewards . At this point nothing like this has ever been done before . Can you imagine the backlash that would occur for the people who bought the voucher early ? The reasonable approach would be to allow all voucher holders to have access to the promotion . <| sep |> Impressive . May I ask for how long you ' ve been doing this ? Bc even if it goes well for a while , if you have enough on hand and a crisis comes around you ' re faster in the trap than you think . Of course it ' s a possibility that you ' re madly disciplined .
