I remember having to go to one of those little community centers for the memorial. I don't know if anyone remembers, but in the 80s-90s it was the directive that the memorial should be held as soon as possible after sun down, so if you had a congregation that shared a hall, you had 2, 3 congregations renting community spaces right around the easter and other spring equinox celebrations.
Eventually the directive came down that we would be required to look for places that were commercial so we could negotiate the place without special decorations and you couldn't rent facilities from churches anymore, and then later came the directive that if you had multiple congregations in the same building, you'd just have to do one after the other, which was hilarious with traffic when 4 congregations need to go in and out of a building with street parking between 7 and 10pm - no time to talk, elders rushed people in and rushed the other congregation out, cops showed up because it was loud and a nuisance.
Looking back, it's surprising how many people woke up over time, just because they got jostled to think when these weird rules and regulation changes happened, about what is ostensibly the most important day to 'true believer' JWs - if they can't even get the rules around that right.
