No Pain For This Refill

(I work as a pharmacy technician. A lady needs her medication refilled but has no refills left. I offer to call the doctor for her but she is mad that we won’t just fill her prescription then and there. Her medication is used for blood pressure.)

Customer: “Since you won’t give me my medication, can I just take this in the meantime?” *holds up aspirin*

Me: “Uhm… no. Aspirin is not the same as your [blood pressure medication].”

Customer: “Why? It’s the same size and color as my medication.”
