Hi - I have found that the staff at FHCs are very helpful and friendly, and they are used to people coming in who know nothing about loading or viewing films. There are usually volunteers there as well who are not church members, and they are all very willing to help. They have some times when the FHC is open only to church members, and other times when they are open to all - you won't get any religious views pushed at you!
Everyone's attention is solely on genealogy.
