A Clear Stamp Of Admitting Their Mistake

(I work in a small pharmacy that is located about three shops away from a post office. Despite being small, it has obvious advertising.)

Customer: *walks straight up to the counter* “Hi. I can’t find your stamps.”

Me: “Uh, sorry, ma’am; we don’t sell stamps here.”

Customer: *immediately becomes frustrated* “What kind of post office doesn’t sell stamps!?”

Me: *indicates to medications surrounding the entire counter* “This is a pharmacy. The post office is just down the hall.”

Customer: “SO?!”

(She then stormed out the door as though we had offended her.)
