Friar, the term 'rip-off' suggests you are being charged more than you expected: this price is not an estimate, it is what you choose to pay (or not).
In your example you have used one person travelling, but if you fill the car suddenly the long Dolmus journey in the middle of winter is not such a bargain. You are being picked up from home and dropped off at home, not having to catch connecting Dolmus. I'm sure there are other cheaper ways to travel, this is an offer which people must decide upon for themselves.
If you took two couples sharing the cost, one of which needed to go to Meis and the other decided to stroll around Kas for the day, this is not an expensive day out with a car and driver at your service.
