TAH, yes I know the system. I take route cabs when I'm by myself, no problem. When we are a party of 4 wanting a ride directly to a particular restaurant, I'm happy to do a charter. The standard fare for one person for the beach to roundabout route or for the roundabout to the cliffs route is JA $130 = US $1.15 (roughly, depending on where you change money). So for two routes per person the fare would be $2.30 US per person, = $9.20 for 4. $12. was not double, it was giving the driver what is to me a modest bonus for acting as a charter and taking us directly to our restaurant and not stopping for other passengers. Certainly one way to look at it is to say "Wow, you paid 25% more than the bare minimum." Another way to look at it is "You paid an extra $2.80 for a more pleasant and comfortable experience." I look at it the second way, and am completely OK with it.
