If we want people to refill reusable bottles, it needs to be easier than buying a bottle of drink. That means a) not needing a bloody app to find where you can get water 2) water taps/fountains in the well walked passages of the station so you can fill as you go past and don't have to detour. iii) not have to ask someone to fill your bottle for you.
@quixoticgeek yeah, did not manage to fill up at Amsterdam cs, even when asking around.
@quixoticgeek thanks and indeed. Just tried finding one in paris Montparnasse, no luck.
