Nothing in Snopes about this but it's an interesting story if true. There were a number of blogs which reported it in a Google search. Please comment if you know any details or the veracity of the story.
ONLY IN TEXAS ... Texas Beer Joint Sues Church in MT.Vernon, Texas . Drummond's Bar began construction on an expansion of their building to increase their business. In response, the local Baptist Church started a campaign with petitions and prayers to block the bar from expanding. Work progressed right up until the week before the grand reopening when lightning struck the bar and it burned to the ground! After it was burned to the ground by the lightning strike, the church folks were rather smug in their outlook, bragging about "the power of prayer", until the bar owner sued the church on the grounds that the church ... "was ultimately responsible for the demise of his building, either through direct or indirect actions or means." In its reply to the court, the church vehemently denied all responsibility or any connection to the building's demise. The judge read through the plaintiff's complaint and the defendant's reply, and at the opening hearing he commented, "I don't know how I'm going to decide this, but it appears from the paperwork that we have a bar owner who believes in the power of prayer, and an entire church congregation that now does not."
