Let’s say, hypothetically, that a regular latte at Starbucks costs $2.65. Let’s say that there’s a separate menu item posted called “Vanilla Latte” and it costs $2.95. Let’s also say that a regular latte with “syrup” (vanilla, for example) is $2.65 plus $0.30, or $2.95. Why then does a “Vanilla Latte” cost reader Jayne $3.25?
