All he expected was obeying the church rules (no alcohol), some sort of donation, and a little help cleaning up. He ran shuttles but wasn't a taxi for thru-hikers at any time they wanted. So if you hear something bad about Bill or the Hostel, take it with a grain of salt, the guy is a trail angel IMHO, but he isn't your mother.
