ummmmmmmmmmm
i'm not exactly sure what you're referring to.
first of all,
there is NO *official* rest-stop at BullsBay
in fact,
there's no *official* rest-stop any-place between the airport and Negril.
I don't know all the in's & out's of the situation(s) and/or *arrangement$*/*understanding$* that have been set-up between drivers and businesses, BUT my *guess* is that drivers will steer their tourist passengers to places where they have a "..one hand washing the other.." relationship ...... and/or the stop/business could/may belong to a family-member (e.g., brother, mom, cuzin, wife, etc etc)
that said,
within the BullsBay area, two places come to mind:::: The Golden Apple and Global Villa..... Yes..!!.. they're both still there,,, doing VERY WELL, too.
a likkle further down the road,
is a place that sits road-side
at the bottom of a looooooong white staircase ::::: it too is still there doing bizness
my experiences with all those places (above) is that they mark-up the prices significantly, to accommodate the foreigner/tourist with heavy-heavy pockets/pocketbooks/purses/wallets ...... when right next door, and/or just a couple steps down the road is another *local* establishment with a very-different pricing scheme, (i.e., more local-friendly).
