Jehovah Witnesses have been trained to refuse any literature when they are out witnessing. They simply will not take what you want to offer them.
However, there is one thing they will take…and that is your phone number. And there lies your strategy.
Toward the very end (not beginning or middle) of your conversation with them, ask them if they would be willing to meet again to talk. Typically they will say ‘yes.’ Then immediately take the initiative and take out of your pocket a tract or other piece of evangelistic literature and write your name and phone number on the back of the tract, and give it to them asking them to be sure to call you for a follow up meeting.
Don’t ask them if they will take it. Just give it to them and say goodbye.
Be prepared beforehand to have a tract and pen ready for the end of your conversation. This tactic may not always work, but it will sometimes.
It is a strategy that God may just use to save their soul.
