How wonderful that you have given so much of your time to church, and enjoy doing it at the same time. I'm on a funeral committee for our church, and it requires a 6 - 7 hour day, it can be very exhausting, especially if only one leader is working the funeral. We haven't done this at our church services yet, but I have heard of a "Potato Bar", similar to a sandwich bar with all the fixings for potato toppings. The size of the potato is significant, and of course you would go though a lot of butter and bacon bits.
