In the US over the past couple of decades most fast food restaurants have moved their soft drink dispensers from behind the counter to in front of the counter. Presumably, this results from the fact that labor has become relatively more expensive over time while the syrup that underlies the soft drinks has remained quite inexpensive, so that there is little point to, for example, spending the time and effort to charge for refills.
The puzzle is: why has this not happened in Denmark.
I'll post a candidate answer tomorrow.
