I was going to start a new thread about this but will just add to this one.
I never knew anything about these trolley carts till I read posts here. However I did see one at a shopping complex last year.
I just started my 3rd week of nursing school at the local college. On Wednesday for the last three weeks a different Elder and their wives setup a table and two carts. They just sit there; rarely do I see anyone talk to them, nor do they attempt to engage in conversation. They usually are there from 10am to 2pm. This is so easy to get the hours in. I would've so much rather of done this as a child than knocking doors. Much less intrusive and embarrassing.
I've had interactions with all the local elders last year as I let them in my house to discuss some topics. So I know them by face. However each time they visited they refuse to answer my questions about the GB so I finally ended the waste of time. The funny thing is two of the Elders there were the ones I complained to about The Organization stance on higher education. They blast higher education but yet will go to the campus to preach to the students. I feel like pulling up GB on my tablet during royal commission, but not worth even acknowledging them now.
