Agree with Jim, some people should carry a calendar and calculator, they entered in October so common sense should tell them 90/180 started then.
110Tl each, not bad, it is Turkey and you expect to be fined, ?
I have never ever been fined as much in my life as there in Turkey, I now have a contingency fund for just that (for those with a sense of humour bypass it is a joke, except for being fined)
