If they know that, why on earth would they buy something they will never use.
Because the uber-dubs for some insane reason believe that you must touch the glass and plate. Before I started my fade I remember the congregation where I was the "servers" would pass the glasses and plates, then one would hand the glass or plate to the speaker who would promptly hand it back, then the servers would all sit down in the front row and the speaker would leave the platform to hand the glass and plate to the first server so they could touch it as they passed it and then the speaker would take it back to the table. The last time I heard anything about their new Zoomorial they are pretty insistent that to be an approved viewing one must also have wine and crackers in front of them so everyone can see that they have them.
