(A couple approaches the counter.)

Me: “Can I help?”

Customer: “Yes, can you give me advice about his stool?”

Me: “I’m sorry, I can’t give medical advice. Perhaps you’d like to speak to our pharmacist, or consult your doctor?”

Customer: “No, I’m sure they’re very busy. I just want someone to tell me if it’s normal.”

Me: “The law says I can’t give advice. Let me get the pharmacist.”

Customer: “No, really, I have some here.” *whips out a clear bag of poo on the counter* “See, it’s all gritty. That’s not normal, is it? Do you have pills for that?”

Me: “Ma’am, you might want to take that to your doctor. We can’t accept biological waste.”

Customer: *to her husband* “See, Joe, I told you it was wrong. That’s why I save them.”
