The assembly provides flexibility in constructing and assembling, for example, a service station or service island. The modularity of the assembly allows for the repair, reconstruction, and adaptation of the modules before or after the initial installation. The assembly further allows for the construction of stations with a variety of structural and functional configurations and combinations. Modules and stations are interchangeable for reasons such as form, function, appearance, size, etc. 
   A variety of first modules or utility stations (e.g., a waste container, trash receptacle, bin, storage cabinet, container, windshield service stations, housing, etc.) may be selected for use in the assembly. The selection may be made according to desires, preferences, or other functional concerns. For example, in a gas or service station, a waste receptacle may be useful, and desired as the first, lower module. An interface (e.g., a riser, extension, frame or member(s), coacting elements, fasteners, etc.) may then be coupled to the first module. The interface may include a surface (e.g., a mounting member, mounting plate, universal mounting plate, etc.) or other configurations for attaching a variety of selected second modules. The FIGURES illustrate that a variety of second modules or stations (e.g., an upper module, portion, station or cabinet, or a side module, portion having a variety of different sizes and mounting configurations such as differently spaced mounting points, differently spaced apertures, differently spaced hooks, differently spaced brackets, etc.) may be selected for use in the assembly. This selection may be made according to desires, preferences or other functional concerns. Furthermore, if there is a change in need or desire for the assembly, the various modules may be replaced or reconfigured relatively easily with other selected modules. 
   Various configurations of assemblies may be used in commercial, residential, or industrial facilities, including gas stations, service stations, garages, warehouses, public areas, parks, near rest-room facilities, etc. Furthermore, the assemblies may be adapted for indoor or outdoor use.
