My husband has been a delivery driver at the local pizza place for over a year. Whenever anyone asks him for his best crazy work story, this is the one he tells. One night, about two weeks after he starts working there, they get an order for pickup from a guy over the phone. My husband takes the order, hands off the receipt, and then fusses around for a bit doing other things. Then, the phone rings again. hands offはどのような意味でしょうか?
