Just back from GA, no car hired this time due to excessively high costs for all the use we would have made of it, so used train a lot and were always charged the correct fares, 4 adults plus 2 children aged 8 and 11, plus one "baby" aged 2 and a bit, should have been 21 euros in all, some times he just took the blue bill and waived the extra 1 euro, I suppose it depended on the mood a bit and interaction with the driver to whom I always speak in Spanish, but whatever the case no complaints.
