Valet parking is a service provided to customers of an establishment where possession of the vehicle is taken in the right-of-way for purpose of parking the vehicle and/or returning the vehicle to the operator. Typically, there is a fee charged by the Valet Operator for this type of service, but that is not required. There are established Valet Parking zones in the CBD and new applications for zones are evaluated as to location and proximity to other Valet Parking zones.
A half sibling is a brother or sister who has one parent in common with you (eg: you both have the same mother, but different fathers). A step-sibling is a sibling who is related to you only by marriage of parents. In other words, your mother or father marries somebody else who already has children.
A half sister is your biological sister but she has a different parent. Like if you have the same mom but different dads or if you have the same dad but different moms. A step sister is your step mom or step dad's daughter but she's not related to you. She is only related to you by law.
