Right. A slow-leaking flat, which I noticed on Monday after work. I was able to ride home, although I had to pump after every 6 kms or so. LBS was closed already, so I went home, took the rear wheel inside, patched the puncture, put the tyre back on rim and inflated. Seemed to hold ok.

Had an uneasy feeling about it, though, so I did not put it back on the bike yet. Next morning (today, actually) I checked the tyre: empty. I bit the bullet and took the bus to work. I visited a bike shop during lunch and bought two spare tyres, paying roughly 25% more than I would have at the LBS.

Please note, I am not going to ask "what next" this time.
