Well, it seems that someone who takes the "cheap" ride to Negril from the airport has to pay $5.00 US for a Red Stripe and someone who takes a charter ride (Clives etc.) pays a likkle more then pays nothing for a Red Stripe (in the price of the ride) or (at least) a lot less.
One person's "scam" is another persons "cost of doing business".
Like the old oil filter ad.... "Pay me now or pay me later".
