Seems like you chose to leave out the part that said this behavior was normal, no matter where the polling place was.
“The ban on caffeine is no different than forbidding smoking, she said. Whether it is a church, synagogue or mosque, “we abide with their rules.” Reed said occasionally there are public requests to cover up crosses or remove religious materials from walls or bulletin boards of churches, but the choice is to honor the host. Some, she said, may be offended, as occurred in 2004, when people voted in military armories and President Bush’s photo was on the wall at the same time he was on the ballot.”
Banning COFFEE normal? Quite far-fetched. However, IMO, there should be no polling in places where religion of any kind sets the rules for those not of that religion. Specifically because THERE IS NO ALTERNATE CHOICE FOR VOTERS IN THAT PRECINCT!
And I wouldn't be comfortable if ONLY poll workers of a specific religion would choose to work under these circumstances...never know when a candidate of said specific religion would need some extra "help".
Move the polls OUT of religion-controlled venues.
