Patron: …and when are these items due?
Me: 3 weeks, so January 29th.
Patron: Wow! Is that three weeks?
Me: Yup. 8 plus 21 equals 29.
Patron: You wouldn’t think it, would you?
Me: I… would, actually.
Patron: Wow, let me write that down. That’s amazing.
Me: I just handed you a piece of paper with the dates on there.
Patron, scrawling dates on their receipt that already has the dates printed on it: This is just incredible.
