Ever double-check your total at self-checkout? One Walmart shopper caught a wild $85 overcharge when the card reader showed $193 instead of $108! She yanked her card just in time and had to get an employee to fix it. Turns out, tech glitches like this aren’t rare—Walmart even settled a $45M lawsuit over overcharging. Moral of the story: always check the card reader before you pay, because these “accidents” never seem to work in our favor! #Food #Walmart #SelfCheckout
