There has always been limits on the Dolmuş it's just that they are rarely adhered to unless the Jandarma are operating checks. Then all efforts to confound and confuse come into play with urgent exchanges taking place over mobiles and people encouraged to duck from view, or a second Dolmuş appearing from nowhere and passengers are changed over until past the check and then reloaded back onto the original Dolmuş and the second Dolmuş disappears to cover for the next one.
All very well and good until there is an accident of course.
I spent my first five years living here using public transport and have seen every trick in the book to maximise fares.
My pet hate was that if they didn't have the correct change it was somehow my loss not theirs, like they aren't already probably the most expensive in the whole of Turkey.
