Customer: *holds up two bottles* “What’s the difference between these two medicines?”

Me: “The one on the left is a capsule; the one on the right is a tablet.”

Customer: “I mean, which one would be better?”

Me: “They’re exactly the same medicine, just in different forms. Most people buy whichever one is easier for them to swallow.”

Customer: “That’s just stupid! How can you swallow a bottle?”
