34saving, as long as whatever comes up allows you to pay by credit card--and you can pay that card off before any interest charges accrue--there is nothing wrong with that ideology. In fact, I use my credit cards for everything I can--down to McDonalds purchases--so I can track my expenses easily at the end of the month and I earn 1%-5% back versus nothing for cash. However; there are a few places that I frequent that for whatever reason still don't accept credit cards and in those (albeit rare) instances I would be out of luck if I relied solely on my credit card for my backup plan. I relish the day when I no longer have to write out paper checks--yuck!
An example would be the plumber--he doesn't carry around a credit card machine with him and requires payment before work commenses, hard to do with a credit card.
