I still have a small plastic document holder with tracts, envelopes and some time slips in my drivers side car door pocket. This left over from another life when I was Gung-ho for the Truth™ ( no idea why I held on to them other than due to my gradual departure and knowing they could have some 'counter productive' use some day ) Have yet to run into any carts but I think these items could be used creatively hehe ! Maybe fill out and present a time slip to one of the elders present.. or maybe just ask them where their hours are at for the month and jot them down. Guaranteed to freak them out especially if they don't know you hahaha !!!!!!
PS : Elder above looks like a Kool-Aid drinking pioneer elder I knew that would snap his britches at how great he is for the Truth™ with his generous airline maintenance tech's pension money coming in every month..
