I agree.
Waiting until you get a puncture is all very well if it happens near a railway station and you can jump on a train back to Ilkley (in my case) but if it is 20 miles from home on a narrow busy country road in pouring rain and it is getting dark you might wonder what exactly you were saving a few £pounds for.
Brett and I share an anecdote where I had a puncture on both wheels and I was walking the ten miles back home in the rain and he drove past me thinking "Poor ******!"
(Although the story had a happy ending 'cos Brett is a good guy).
