I am Catholic.  When I asked to use the LDS cannery services, that never came up.  I was given dates and times that my particular "area" could go do the cannery.  The cannery is a warehouse of food.  They give you a menu and you can purchase whatever and however much you want.  Then you get into an assembly line with other people from your area and everybody cans everybodys food.  
I call them LDS as if they are a different people.  But, they are my friend.  I am very thankful that I was allowed to use this service.  
The amount of time, money and effort that the LDS church puts into preparedness is wonderful.
