Did you look online?
Maybe the machine was out of cash?
I just assumed it was out of cash because of when it was. I knew my account wasn’t! LOL Now, if I had tried 2-3 places and got the same result, I really would have been suspicious.
Our local Kroger (think HEB) has recently put up a sign at the self-checkout registers that they’re card only-they no longer take cash at those registers.
