Volunteer Fire Department

My cousins lived in the country. Their house was not serviced by water lines. A reservoir on their roof collected rainwater and they had to be very careful with their consumption. Toilets were not flushed unless there were solids to be disposed. Not all the guests at the family reunion that year were aware of that, and the reservoir ran dry. One of the guests worked for the volunteer fire department. He drove into town, came back with a fire truck and refilled the reservoir. Needless to say it was a memorable reunion for the cousins of the youngest generation.
