Lemon play

Patron: “Why can’t my son play with the lemon? ”
Me: “Because it’s an actual lemon.”
Patron: “It’s just a lemon.”
Me: “That someone can step on.”
Patron: “No one’s going to step on it.”
Me: “Ma’am, it’s food…produce. Not a toy. There are actual toys to play with over here.”

WHY IS THIS EVEN A CONVERSATION?
