Maud made her flower sandwich and presented it to Taste Explosion.
“Hmm, good presentation. The diagonal cut is straight and the ingredients are evenly spaced. The toothpicks are a nice touch. I'm sorry to say though that our hypothetical client can't eat it. He's allergic to bread.”
“What?” This revelation did not alter Maud's flat expression.
“Yep. Regardless of how cheap or expensive the flowers are, you've still offended him by offering food he can't eat. Now you're down a customer and your shop is going out of business.”
“Oops.”
“It's true that ponies have different tastes, but you'll never know what those tastes are unless you ask. Never assume you know what another pony wants unless you already know them. That's a fairly basic thing to get wrong. I'm going to have to ask that you pursue a different field of study.”
Drat.
