I live in a pretty market town in Germany with lots of tourists and cafés for them. We who live there have them well marked out. There is one for the twenty somethings, another for the older generation and the large one which we call 'screaming kids' Even this one is not so bad as decribed on GN but I avoid it except when I am pushing a buggy myself.
I take my two GDs out for ice creams where they live and they sit in place while eating. On the whole it is expected here, but I coudn't speak for burger bars etc as I don't go there anymore.
