<prompt> Human: On paper gas credit cards sound great. However I notice that no one on this sub-reddit recommends them. Why is that? There shouldnt be a problem if you only use it for gas and pay it off every month right?  <response>: Theres nothing wrong with gas-branded credit cards, but you can usually find non-gas-branded credit cards that offer greater rewards on gas and dont limit the gas stations you can use.
