In real life the wealthy merely need to imply the things that Colin had to say for the story. If you’re influential enough, you don’t have to actually say anything. You just act as though you have permission to do as you please. The scandals around the British royal family are just examples of usually less experienced, younger, and often lesser members who go just a few steps too far (Naked Harry, Nazi Harry, topless Kate, etc). People who work in all forms of customer service (retail, food service, hospitality, etc) are used to accommodating varying degrees of misbehaving patrons – people who would never otherwise scream at a stranger feel no shame when they’re upset when they can’t return something in a store without a receipt or when weather has delayed an airplane (and most of the time the person behind the counter just takes it calmly even if they’re seething inside).
