If the driver attempts delivery and the recipient is not home, the driver can do one of several things. He can attempt to contact the recipient by telephone if a daytime number has been provided. He can leave the flowers with a neighbor and leave a notice on the recipient's door. If none of these options is suitable, the driver can attempt to contact the sender to arrange for another delivery attempt. Flowers are never left where they can be exposed to excessive heat and sunlight, blown over, or stolen.
