<prompt> Human: Besides the obvious groceries, gas, restaurants, what else do you use your credit card for? for e.g. do you pay your utilitycableother bills on it? Is that a good idea? Im thinking of getting a cash back CC and paying all my monthly expenses on it and of course paying that amount off in full every month. Downsides to this approach?  <response>: Everything that accepts a card without a fee that exceeds my rewards
