+1 for bining punctured tubes. I carry two spares and a pack of Park instant patches in case I run out of spares. I never fix a tube. Given the lengths some of you seem to go to to ensure a good patch confirms that my time is too precious to spend time fixing something that only cost £2.50. Less than a decent coffee.
1. A tube can be patched in minutes, and it is some of us find it theraputic.
2. I can't afford to buy cups of coffee unless I save some £2.50s.
3. Some tubes cost consderably more than £2.50.
4. It's environmentally friendly to repair rather than replace.
5. £2.50 is far too much for coffee. 
Interesting how the tube:coffee price ratio varies.
Here, decent tubes are 200 rupees. Indian made ones, which tend to be a bit leaky, are 50 rupees. That's about L2.50 and 60p respectively.
A cup of coffee costs 5 rupees at the roadside, 9 rs from the India Coffee Board Coffee House, or a whopping 25 rs from a Western-style cafe.
It can thus be concluded that the sub-continental cyclist has more coffee-drinking incentive to repair tubes.
Or simply take them to the local puncher wallah who will mend them for 10 rupees.
