No Fran it was not luck of the draw...we went on the Dolmus again yesterday and today and more people were paying with cash than using a card, and yes you are right there is a recorded message in Turkish and English saying they no longer take cash, and it is 5 lira each cash, we will next be going on the Dolmus on Saturday and we will pay cash , if you go on the Dolmus and give the driver cash you will see what mean
