Im writing this while on the train in Amsterdam, love my travel so far, but those small cost that they charge is too damn much, 0.5-0.7€ to pee, even at macass and HJ after you buy their meal, and especially at the train station AFTER you bought the ticket.
In Au some store might lock their toilet but if you buy something, they will happily let you live in it(just an expression) and water, wow, we have free fountain every where in Melbourne and in here one bottle of 0.2l is like 3,4€, and water is not free in restaurants, even softdrink came in smaller size too compare to i would say standard 0.5l.
Dont get me start on public transport, amazingly expensive, i know im on holiday but the price is shocking.
My final word, i read a lot on internet that our living cost is too expensive and one of the highest in the world but wow, nothing compare to what im experience here in Amsterdam. What is your opinion on this subject as our basic water needs is kind of free and our public toilet is high tech automated
Quick solution
Stop buying water and you won't need to piss. I just saved you a lot of money.
And public transport is much cheaper, Beer is cheaper, Food is cheaper.
Buy tickets from machines, not people if you have not already worked that out.
You win some you lose some
