I always carry both a spare tube and a patch kit, and both a CO2 cartridge and a frame pump. The first flat gets a new tube and CO2. And I can be back on the road in under 5 minutes. The second and subsequent (yes, it happens) get a patch and a pump. By that time, I'm already going to be late, so I might as well call ahead and take my time.
