(A man was picking up a prescription for his infant child.)

Customer: “How much did you say the prescription was?”

Me: “$49.99.”

Customer: “What’s the difference between this and what I can get over the counter?”

Me: “There’s no cough medicine you can give your 8 month old, sir, other than this.”

Customer: “Well, what’s in it?”

(He picks up the prescription papers and starts rustling through them.)

Customer: “If I can buy everything that’s in it over the counter, I’ll just make it myself.”

Me: “…excuse me?”
