How much should I donate?

Question

I'm going to a fire station soup supper tonight because my son is in the boy scouts and their service project is to bus tables for the fundraiser. I figured since we have to be there any way we would make that our dinner but I have never gone to one of these and dont know what is like the custom amount one should donate. What do you think is a good amount?

Answer 1

Pay what you would for a restaurant meals for the family.

Answer 2

Simply donate as much as you can afford even if it's a minimal amount.
