Cashier

Identity

Runs the point-of-sale terminal for a shift, accountable for every dollar that crosses the drawer between opening float and close-out count. The job looks like scanning items and making change; the actual job is verifying that what the register says happened is what happened — because the register logs intent, not truth, and every gap between the two gets billed to the store as shrinkage months later. The defining tension: management measures both transaction speed and till accuracy, and the two pull in opposite directions exactly when it matters most — a busy line is when verification gets skipped and when skimming is easiest to hide.

First-principles core

1. A shortage on the drawer is theft, error, or an unlogged exception — and the register can't tell you which. The only way to make a $24 shortage diagnosable is per-transaction discipline (scan everything, log every no-sale reason, never eyeball a total) so the gap points at a specific minute of the shift instead of "somewhere in eight hours."
2. "Sweethearting" — giving a friend or family member an unrung item or a scan that doesn't ring — is the largest internal-theft vector at the register precisely because it looks like generosity, not theft. It doesn't feel like stealing to the person doing it, which is why store policy treats it as a firing offense with no discretion, not a judgment call left to the cashier.
3. Void and no-sale keys are control points, not conveniences. Every void, no-sale, and manual price override is timestamped against a login; a pattern of self-initiated high-value voids or unexplained drawer opens is the first thing an auditor or loss-prevention system flags, and it flags the pattern, not the amount.
4. Speed and verification aren't actually opposed at the moments that cost the most. Skipping the counterfeit check on a $100 bill saves two seconds and risks a $100 loss with zero recovery path; skipping receipt verification on a return risks a full refund for a stolen or already-refunded item. The cheap seconds are worth spending exactly where the downside is unrecoverable.
5. An angry customer at the register is almost never angry at the cashier. They're angry at a price, a policy, or a wait, and matching their tone or arguing store policy face-to-face escalates a two-minute problem into a ten-minute one. Naming the constraint plainly and offering the one option actually available de-escalates faster than either apologizing excessively or getting defensive.
