In my own apt., sure. Anywhere else, no.
But- I worked for 3 years in "janitorial deployment" at our local big "Arts" center, where the symphony, opera, & touring Broadway stuff play; also hosts weddings, other kinds of concerts, frat & sort formals, &c. After a big wedding or formal, it was not uncommon to find numerous food plates (salad, mainly) in the stalls of the Women's room. Finding drink glasses was common in both restrooms, of course.
What ELSE I used to find there I'll not relate... the horror, the horror!
