As you are considering Dutch boys you might like to know the current rate, which is тВм 175,- (about 8750 bath) for the first hour. The next hour is only тВм 100 (5000 bath) more. Is does not go by the minute so a bit over an hour would count for two hours. Prostiution is legal in the Netherlands so 19% sales tax (value added tax) would be added. The boy would of course appreciate a tip on top of that.
