I have a small shop.
Here is a conversation in said shop:
GUY: "Finally! You're open!"
ME: "What do you mean?"
GUY: "You're always closed when I come down."
ME: "You should probably come down when I'm open."
GUY: "You're never open."
ME: "Actually I've been open every day for thirty years except for Christmas and Thanksgiving."
GUY: "Not when I come down."
ME: "You should come down during our store hours."
GUY: "What are those?"
ME: "The hours when you don't come down."
