Isn't the whole idea for ATMs to be available 24x7??? I'm yet to encounter an ATM
that would be turned off on weekends.

You are right, however, what happens when Mr. Karmann arrives on a Friday evening, wants to get cash in a German ATM, it does not work, all banks closed, maybe even on Monday (Germans have lots of holidays).
I ONLY USE ATMs TO CHANGE/GET MONEY, IT'S THE CHEAPEST AND BEST WAY. TO BE SAFE I HAVE SEVERAL CHARGE AND CREDIT CARDS AND PINs FOR ALL OF THEM.
