Unfiltered Story #236318

I work at a coffee shop well known for its green mermaid logo. One morning I am working at the front till when a young man comes up and the following conversation takes place:
Customer: Can I have [signature drink from another fast food place, known for its red and yellow logo, obviously not us]
Me: I’m sorry, we don’t have any of those here.
Customer: Oh, okay. *moment of silence* Can I have a small blended coffee drink?
Me: For sure! One small [name of blended coffee drink].
Customer: No! I want a blended coffee drink!
Me: Yes, that is what [blended coffee drink] is.
Customer: Oh, okay.
*Customer pulls out random coins from his pocket and counts them out*
Customer: I don’t have enough change. *looks at me expectantly*
Me: I’m sorry, but I can’t give you the drink without full payment.
Customer: Oh, okay. *Turns and leaves as I mentally facepalm*
