Well you can define words how you wish to. But that will not change generally accepted definitions. People are defining theism a certain way generally and atheism as a rejection of those concepts is still a coherent worldview.
Most definitions of worship will involve more than mere service though defining worship could still be tricky I suppose. In addition to service I'd say it also often involves an emotional component, devotion, prayers, offerings. It often involves meditation and prayers in an anthropomorphic sense even if said deity or object of worship is not a personal force or being. I'm not saying this definition is wholly adequate or universal but it distinguishes mere service as to a government or job.
