people use water glasses etc placed in public places.Also in office men and women sometimes share food from same plate. What is ruling with evidence.
There is no prohibition in Shariah for males and females to use the same
utensil kept for public usein public places. However, it is against shame
and modesty for a strange (Ghair mahram) male and female to share between
them the contents of one utensil.
