Public air pumps for bikes are everywhere in the Netherlands. Seriously, you'll find pumps out the middle of the woods here sometimes attached to little huts to use.
Almost every bike shop has a pump chained near the front door for public use. There's a number that even have automated air systems. Finding air isn't an issue here (though, be sure to at least look at the valve first, since sometimes they'll be Dutch values and won't work on your road bike). Most bike parking garages have pumps as well in them. And if all else fails, you can swing by the DCR Cave and I've got a couple.
Bike washes though...hmm, I haven't looked for that. But I don't remember seeing any stick out. And I haven't finished building mine yet. On my to-do list.
