Johng,
I can say confidentiality that no Jamaican earning minimum wage will purchase a beer for us$5. That is why I stated that Tony was no longer interested in the local business and will focus on his tourism business.
Being in my position, I have to visit tourism establishments often and I never see other locals at these establishments without a tourist host. The locals simply can't afford it. Even a j$500 Red Stripe is tough to swallow (pun intended).
Drifters has a unique deal. They have the regular 341ml stubby bottle Red Stripe for j$500. But they offer the weird "tall" 250ml bottle for j$250. That makes it possible for some locals to actually buy their own beer at Drifters and enjoy it for themselves.
One of the reasons Red Dragon is so popular is that locals and tourists can mix in the same establishment and our visitors get to mix with Jamaicans on an equal footing.
The us$5 places will make their money but I think an essential feature of Negril may be lost without the local perspective (other than the bartender).
But there are PLENTY local bars to visit not on the beach.
