Be the offpsring of someone powerful. The BBC's Will Grant:
In walks Andrea Benitez, a wealthy 20-something, looking for a table. Told that the one she wanted wasn't available, she threw what can only be described as a tantrum and used the ace up her sleeve, her daddy. Andrea Benitez is the daughter of Humberto Benitez Trevino, who happens to be the federal attorney general for consumer protection. Faster than you can say "do you know who I am?" Andrea had called her father's department, which promptly turned up at our local neighbourhood bistro and closed it down on spurious administrative grounds.
