This is a typical emotional appeal from the Watchtower.
At our hall - we phoned in - the speaker went on and on about his 'days in Bethel service' and what a wonderful privilege it was. And...if you don't have construction skills to assist the project, each publisher can support the project with funds.
My brother said that at his hall an elder was standing in the lobby handing out the Temporary Service applications.
The Watchtower uses the tent revival model to get what it needs from it's members....because it works.
