I doubt they are going to bother buying small glasses to hand out to the celebrants.
OK....Communion in the CofS 101;
1. Senior elders serve bread and wine to minister.
Wine is in siver cups (Ours are four centuries old)
Minister serves cup and bread to all elders...democracy, eh? No-one is 'superior'.
The elders take plates of bread and trays containing the tiny cups, already filled with wine before the service, to the congregation.
It's a lot quicker that way than t'other one.
