I think you're confusing faith with empiricism. It doesn't take any faith for me to try a new restaurant. What it does take is observation and my own intuition/reasoning about the place. Does it have a good reputation? Does it have a good safety rating? Is it a kind of food that I would enjoy? Is it in a price range that I find acceptable? Faith would be more like "Well I know nothing about this place, here's hoping for the best" but even then I could still make a semi educated reasoned guess about the place. For example if its a 24 hour diner it probably serves breakfast. If it's part of a franchise it's food is most likely similar to other places in the same franchise. Just because there may be a bit of uncertainty doesn't mean I need some kind of faith. If the place ends up sucking or a friend that I trust tells me they have a really rude waitstaff then I'll go somewhere else.Faith exists in a lot of forms, you need to have faith in untested people or food, for instance, everyday or you'd never be able to make short journeys to work, the shop or eat. However I think we're talking about spirituality, I think its unrivalled, much of the kind of uplifting experience that most professing athiests have talked to me about arent that attractive and are often a twisted mirror image of the sorts of evangelism which they reject and probably led to their rejecting spiritual faith in the first place.
Faith is not required.
