Political views aside, one thing very noticeable about Donald Trump is that he always seems angry. He is not one for easy smiles, let alone laughs. Instead, he sports a permanent frown, ready with a sharp critique at any moment.
So consider for a moment, Donald Trump being your customer or client. Could you keep him content and actually deriving pleasure from your offering? Or, would he quickly find reason to fling his signature phrase at you: ‘You’re fired!’? Thinking about how to gratify an extremely surly, combative customer is a good mental exercise for crafting irresistible customer experiences.
