Another curiosity is that the invitation only invites people to a "talk" that happens to be on the same date that Jesus died. There is no connection made on the invite that this has anything thing to do with the Lord's Evening Meal or 'Last Supper' Memorial or Communion, as it is often called in non-Jw circles.
Unless a visitor has contact with a JW to explain what will be going on, he will visit a meeting with a 'talk' and then he will suddenly have bread and wine passed his way, all the while seeing everyone else (or nearly so) turning the supposed invite to partake down.
