An assembly includes a structure, a plurality of terminals and a plurality of compliant pads disposed between said terminals and said structure. The flexible portion is coupled to a drain pipe of a building connected to the sewer line, after the elbow connection between the drain pipe section and the drain in a sink in the building has been removed. The sliding sleeve can be positioned in a working position where it surrounds the clamping sleeve and exerts a radially inward-directed force. Key attributes and values are generated such as region and continuous query. Housing the clubs with their heads lowermost lowers the centre of gravity of the bag, and a detachable carriage and optional tractor unit are provided. The resultant amount may be returned to the player in a variety of ways, either directly or indirectly.
