DAE remember when the cash register at my old diner charged 7 cents extra on every $4.99 meal
For one week in July the register rounded $4.99 up to $5.06 instead of $5.00, so at 90 meals a day we took in an extra $45 and the owner blamed the "new tax." A regular named Hank caught it by counting his change twice and showed the manager the receipt. Did your work ever have a math glitch that quietly made money off everyone?
