Cinemax
Internet booking convenience charge has paid for total inconvenience

I have booked the Cinemax ticket through internet booking and convenience charges of Rs.22 has paid. But at Cinemax, Cochin counter we have to keep stay in queue for along to get the ticket coupon. Then why this convenience charge is applicable? Even it take to the notice of Floor managers, no resolution so far...? Either convenience charge to be waived off OR give convenience.
