I have used this change office many times, and to my knowledge have never been short changed, but I have posted this as information, not accusation.
One of the people is a friend of mine, he thought that something was wrong as it was being counted so he counted it again while someone else was being served and found it 100tl short, he challenged the man and was immediately given another 100tl. Later that day we met up with another friend who said that when he got home he found his 100tl short. As I said, best to check it before you leave the premises.
