Here’s a West Texas story from around 20 years ago.
A family was traveling out toward the Texas panhandle and dropped in on a Sunday night Nazarene service. The church had no a/c, and with the temps hovering around 100 dry degrees, the evap coolers (otherwise known as “swamp boxes”) were the only hope of even pretending to be comfortable. The visitors arrived a few minutes late and were amused to see around 20 people sitting on the left and only two older ladies sitting on the right side of the sanctuary. The family moved to the side with ample seating and settled in for the service.
In a few minutes they were melting from the heat and realized that the swamp box on their side of the sanctuary wasn’t running. Now they knew why everyone was sitting on the left side of the sanctuary! After the service they visited with the pastor and he apologized for the uncomfortably warm conditions and the visitor said, “What is wrong with the evap cooler on the right side of the sanctuary?”
The answer: “Oh nothing is wrong, but those two dear saints always complain that they get too cold, so we don’t turn it on on that side of the building.” He added, “the church folks call the left side of the sanctuary the ‘heaven side’ and you can guess what they call the side you occupied!”
