A bag support apparatus has a first support member, a first arm slidably received in the first support member so as to be movable between a retracted position and an extended position, a second support member, and a second arm slidably received in the second support member so as to be movable between a retracted position and an extended position. The first arm is linked to the second arm such that a movement of the first support member toward the second support member causes the first and second arms to move toward the retracted position and such that a movement of the first support member away from the second support member causes and first and second arms to move to the extended position. A scissor mechanism is linked to the first and second support members and to the first and second arms.
