Trip to bikeshop - 15 mins.Because I have better things to do with my time.
Finding hole and sticking patch on - 10 mins. (9 and a half mins waiting for it to dry)
You have to take the wheel off the bike and the tyre off the wheel either way so it doesn't take long. And you have to find whatever caused the puncture anyway, which is surely easier if you find the hole in the inner and line it up with the tyre?
