A woman wears a very low-cut dress while entertaining the soldiers. She bends forward multiple times, displaying ample views of her cleavage. One of these times, she's offering chicken from a platter and asks a soldier if he prefers breasts or legs while her breasts are right above the chicken. The soldiers look at each other, recognizing the innuendo.
