Cover Your Nut Edit Meaning

1.

when a sales person makes enough money to cover expenses.

Came from western days when peddlers came into a hotel and needed a room but didn't have any money. The hotelkeeper would take their hub or "nut" from the wagon as a deposit. If the peddler sold enough, the nut was covered.

It cost me $200 for dinner but the commisson on the sale was $2,000. I covered my nut and then some.
