As noted in a previous comment, it wold be nice to have some sort of evidence of that. Not that it would surprise me, mind you.
I'm a Mormon myself and I find this quite appalling. To set someone up like this and dump them after they've made a serious investment is rude at the very least. What's even more sad to me is that there isn't room to adjust the pub to also work as a restaurant. While I hate alcohol I love going to pubs when I've overseas. They usually have the best food.
Regardless of what's behind this I'm quite sorry for the owner. He should not have been stabbed in the back like this. No Mormon who actually pays attention to the principles of the religion would have wanted that.
