What does "tab" mean? A debt, perhaps?

A "tab" is linked to the idea of an "account" at a store. It is what you owe the store for all the things you have bought! But it also refers to a "bill" or "check" at a restaurant. Ex: Waiter! Can you bring us the tab, please? Ex: John, you haven't paid off your tab for two months. Please, pay it by tomorrow.
