Only until they've finished eating and drinking, Texas...Then they are welcomed.
Actually, what I was having trouble with was that folks would show up to church expecting to eat/drink during services...not that they would be refused admission under those circumstances. I don't think I'd have the patience to treat them as graciously as you were able to do.
It is a cultural thing, actually. Our church has a significant number of parishoners who come from South America. Evidently, the praise and worship services there are held in stadiums, or in large outdoor venues. Folks pack a lunch and make a day of it.
