Your philosophy is different from mine. I'm not controlled by fear. I do want to treat guests respectfully and give them a good experience, but the good experience needs to go both ways. I can't imagine sitting around anticipating guest complaints, or planning for them. Maybe it's just your communication style..it leans to worst case scenarios, and creating problems that are not there. I'd rather focus on repeating the many many positive reviews and what I did right in all those cases. I enjoy meeting my guest needs, in the niche I operate in.
I've been open to a number of ideas, but true....less to yours because they don't address the core issue but all sorts of things that aren't real or might happen. I'd rather deal in facts and the real issue, not make up baseless stories about religious discrimination. I also believe in giving guests wake up calls when they operate in unrealistic scenarios, because if no one does, how do they adjust.
I agree with Sarah that my guest may be operating with some other things going on. It is apparent his version of normal isn't the same as mine, and his self awareness may be on the low side. The world may be overwhelming for him and he found a (too) comfortable place to duck into. That is a story that fits for what I'm seeing., but still an unfounded story.
I apologize if I'm more black and white than you. So much is extraneous stuff suggested that I can't do anything about. I'm not discriminating against his religion....that is nonsense.
