I’d find it hard to believe that no one who’s cried “ussar” in this thread hasn’t ever bought a cut up watermelon in a grocery store.
i guess you feel that way because of the circles of people you find yourself in
im not even one of those “crying ussar” but i would not buy cut up watermelon from a grocery store, nor would any of my friends. there is certainly room to say its mutar but i would absolutely not eat such a thing.
