A coin grand slam is something that any lazy schmuck who's worked a cash register knows all too well. It is the much-maligned phenomenon that occurs at the end of a transaction when the change that you owe back to the customer requires you to use at least one of each of the four principal coin denominations (quarter, dime, nickel, and penny) ... thus making you hate your job that much more.

Cashier: "Holy-bejeebers another coin grand slam?!? That's my third in a row :( I can't take this s*hit anymore ... "
