Often in the past, after missing many months of meetings, I just showed up at the hall, and I had such a hard time finding a Watchtower magazine, just to follow the study.
Even elders were trying to find one for me, and sometimes there was just one left, and often there was none, so I remember being given one from a witness who decided to follow with his spouse in her magazine.
What I'm getting to is that they don't have tons of magazines at the hall, just there waiting for some newbie to show up.
I wonder why they go door to door, if they can't even have a couple of spare Watchtower magazines incase a stranger just showed up...
