I guess when I was in, me an the wife were the totally opposite. While we gave generously, as we usually sat with familial relatives, we were appalled that they gave barely enough to cover the costs if at all. . We often saw them counting pennies and change to donate for the food surprising because they had better jobs and were a whole lot better off than us. These same family would often get enough food to eat during their drives home also.
We knew that food by the donation arrangement wouldn't last though as we saw many who would get up before the end of the last talk before lunch to get food, then get so much that if you weren't there for the first few minutes you got nothing. that coupled with the typical cheapskateness of witnesses it ws only a matter of time before the even newer simplified arrangement of bringing your own foos would be born.
