How do I stop freezing at the register when something goes wrong?

You fumble the buttons, and when a transaction goes sideways your mind goes blank. It feels awful, especially with people waiting. But hear this clearly: freezing is not a character flaw. It is what a new brain does under pressure before the work becomes second nature. Everyone who is now smooth at this once stood exactly where you are.\nThe freeze happens because you are trying to remember everything at once while also feeling watched. That is too much to hold. The way through is not to get calmer by force. It is to make the steps so familiar that your hands know them even when your mind blanks. Familiarity is what melts the freeze, and familiarity only comes from repetition.\nSo practice when the pressure is off. On a slow shift, or after hours, walk yourself through the tricky ones: a return, a void, a price check. Do each a few times until it feels dull. Boring is the goal. The transaction you have done twenty times in calm cannot freeze you on the twenty-first when it is busy. Rehearse the hard ones before they find you.
