Just put hot water in the bath? To keep it warm
Don't be ridiculous. What sort of a nutter sits for two hours in a bathtub, continuously letting the water out and topping it up again. Still I suppose Dutchmen are known for smoking a lot of the old Mary Jane.

Steady on now! That's stretching it a bit :)) They can be quite brusque to downright rude, but no more so than many other nationalities. Equally they can be very pleasant. Actually, I find the older generation 50+ often have better manners and social skills than the younger ones.
They are not bad at all,a myth
They're atrocious. Not a myth, a fact backed up by stats. Most dangerous roads in the EU. They have an appalling record for road deaths per 100,000 people.
