They expected a nice tip, believe me. And why not? We lived like beggars.
I remember the italian/american family visiting our missionary-home, with three kids, sent by the bloody branch on a saturday afternoon. Canceling all bible-studies. They were " checking where to serve the need was greater". My ass. First needed to loose fifty pounds a piece to walk whole day in the tropical Sun.
Anyway we made pizza and a bunch of pasta for the whole 1000 pounds group, they didn't even help with the dishes.
