Leading on from the other discussion... I had a long and complicated epic this morning where I ended up in Leith after a 14km run (the foot race sort of run), with a bike with long-neglected flat tyres.
Not only does Leith Cycle Co let you use a pump, they actually have a pump chained outside on the street, so nobody was hassled and I was able to get home in time to mitigate my fail.
Huzzah for Leith Cycle Co!
