Actually,
I did the opposite today
I was doing a brevet, and was about 60 miles from Home. I had a flat , and my first attempt to repair it resulted in a exploding tube I got successfully fixed on my second attempt. But then I didn't have any spare tubes.
Later on, riding thru Hemet, I ran across a sidewalk cyclist. I noticed that had fairly new Raleigh. so I asked where the LBS was and made a detour to pick up some more tubes.
