Yes, the city wants people to pay their bills; but what about when the bills are in dispute? Some, like the Rev. Alvin Gwynn Sr., president of the Interdenominational Ministerial Alliance, cave in. As his bills mounted at the Friendship Baptist Church while he challenged their accuracy, Rev. Gwynn finally paid thousands of dollars to avoid a tax sale. Though the city has acknowledged that it miscalculated the bill, he said, he has found no relief, and the church, which has only one person on site most days, is billed for 4,900 gallons of water a week.
