Presuppositions as Questions
This technique is only effective if you use it in appropriate situations. For example, if your server approached you and said, “A coffee would be really warming, wouldn’t it?” as her opening statement, you might find that strange, patronizing, or even offensive and condescending.
However, if you were trying to decide whether to have a soda or a premium cocktail, and the server asked, “What can I get you from our premium selection?” you might be swayed towards the premium cocktail.
