In 1973 and '74, I worked on a farm.
There was one large, yellow Igloo water cooler with a block of ice inside and one tin cup.
Every worker - white, black, Puerto Rican and "Texican",
drank from the same cup. Nobody got sick or caught a disease from it.
Different times.
You used a cup? We would give the valve a quick squirt to get the dust out then lean under to get a drink.
