Approach to the station will have signs saying "throw your empty bottles here" or, if it's the Pirate Station, some vguely amusing abuse. So you slow down a bit, you chuck your empty bottle(s) in the net. Ahead of you will be a line of friendly faces (or Schmunkee and her evil henchmen), holding out full bottles and shouting "High 5.... High 5". Make eye contact with one, give them a clue you're incoming, grab the bottle and push it in your cage. After that you'll have a repeat line shouting "Water... Water". If you drop your bottle, grab another. If you're going slowly enough, you can get two. After the water is another string of helpers holding gels, half bananas and energy bars and shouting to let you know which. Grab what you want, stuff it somewhere, and get yourself moving. There's another opportunity to jettison empties or litter at the end of the station. They also have a little mech station for any fixes you need to do, and some chemi toilets.
They're good as gold, Slokey, as long as some tee-wat doesn't come screaming in like an exocet on his TT bike at 22mph shouting for a refill of their speedfill
