Worship (verb) show reverence and adoration for (a deity); honor with religious rites.
I was just thinking about the two meetings a week. The first one consists of the "congregation bible study" which involves reading a paragraph, answering from the paragraph and moving on. Essentially it is studying a book. The next, the Theocratic Ministry school consisists of short talks based around a bible theme, usually presenting the current WT view on doctrine. The last part, the Service meeting basically tells JWs what to do in the ministry and tips about return visits, studies, and door to door. Very sterile, clinical and nothing that resembles "worship".
On Sunday, you have a public talk, which seems to be 10 minutes of how bad things are and 20 minutes bashing other religions and then the "hope for the future" very doctrine oriented. Cliche Proof texts are read and twisted to fit what is being discussed. The WT study is classic indoctrination techniques. Read a paragraph or two, read a out of context scripture, and have the people answer the question based on the answer provided in the same paragraph.
Perhaps the prayer could be considered worship, but most of these fall short of that. The only thing I suppose that could be considered worship are the piped in, tinny sounding songs. For being called a place of "true" worship, the KH seems to have very little of it going on within its 4 walls..
