I have Walmart pay set up on my phone but I almost never use it. This morning I was distracted by my dog before leaving for work and forgot my wallet. I was running very low on gas and had planned to stop and fill up near my office 40 miles from home. Pulled into the Circle K and realized I had no wallet. DOOOOH!!! What to do??? Then I remembered the gas pumps at the Walmart neighborhood market near my office accept Walmart pay. Pulled in, scanned the QR code on the pump with the WM pay app, and filled up. Crisis averted!
