Don't say never, especially with flats
I had flat kits dedicated to each bike, including the bikes used by my wife and son who won't even change a flat for some reason, so I'd say the same thing. Until I bought another bike and moved one kit to it. Now the old one doesn't have its own, and the last three or four times I've used it I've made the same "bad call" of just going on. It's just luck that I haven't flatted.
