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 I have added a few taps and #water dispensers to #openstreetmap
@quixoticgeek I've switched to pocketmaps for offline routing but maps are still big so I compile my own for smaller areas but it takes so much CPU time. I ought to publish the Makefile for possible improvement
