There are not all that many Mormon Temples, but one is, oh, 2 doors down from work. I personally have found them to be good neighbors, even though we have different beliefs (heck, I'm a right wing nut job, and I'm a UU - I expected an anti-matter explosion with that one).

Personally, I've found that if you give them a BIT of respect, they get to know who you are, they tend to let their deeds to the talking, and don't go into the prostelitizing mode that many people dislike. I actually find it nice to deal with quiet respectful people in the heart of Manhattan
