A Failed Delivery

(I work in customer service for a big online store. Since the store is only online, we get a lot of customers calling or emailing us on a daily basis, and because we pay and do all the shipping, we also have to call [Delivery Company] daily. I absentmindedly answer a call:)

Me: “Welcome to [Delivery Company]. This is [My Name]. How may I help you?”

(A coworker looks toward me in wonder, notices what I said, and tells it to the others. They all start laughing.)

Customer: *on phone, in wonder and amusement* “[Delivery Company]?! I thought I had called [Online Store]!”

Me: *noticing what I had said* “Sorry, it’s been a long day. Welcome to [Online Store]. How may I help you?”

(Not my proudest moment, but at least we were too busy for my coworkers to start teasing me about it.)
