Should Have Kept Zip!

(I work at a very popular discount store in a shopping center. We get employees from other stores in here all the time to get drinks and snacks before their shifts. A woman wearing another store uniform comes up to my register with a soda and chips when I notice something. I finish scanning her order and motion her towards me, covering the side of my mouth to let her know her zipper is down without embarrassing her.)

Next Customer: *slams her hand on the counter* “No, do not do this. I’m very late and you guys always do this.”

(I look at the customer, slightly confused, but tell the girl again since she didn’t hear me the first time.)

Next Customer: *gets angrier* “Seriously?! I’m late, and you’re sitting here gossiping! You guys always do this!”

Me: *turns to her* “Ma’am, I have never met this girl in my life before, but she’s just about to go to work with her zipper down. How would you feel going to work, interacting with customers and other employees for eight hours, and going home, just to find out your zipper was down the entire time?”

Next Customer: *stutters and turns bright red* “Well… I’m late and I need to go.”

Me: “Okay, just a moment.” *turns back to the girl and finishes her transaction*

Girl: “Thank you so much, [My Name]!” *smiles and walks away*

([Next Customer] was quiet throughout her whole transaction, still beet red.)
