In that case, forcing the businessperson to run their lawyer clock and lose money by hour and getting nothing pragmatically useful back goes a long ways. In your case, you're up against bureaucracies with deep pockets, so that strategy wouldn't work as well. Also, savvy businesspeople tend to recognize "intelligently crazy" and become a lot more wary when coming across that personality type.
Someone at the HR/legal department might not flinch at at burning $20,000 in legal fees for a moral victory if they're antagonized, but in the commercial real estate world, they'd back off from that. You gotta understand the context and leverage and desires of everyone involved - in this article's case, it's not about antagonizing the lawyer so much as sending a clear message to their client ("I'm going to force you to pay lots of money in legal fees and not even flinch") - usually at that point it's not worth bringing a case, because the opportunity cost of many burnt hours and running your lawyer clock while the other side isn't running theirs is scary. And it doesn't even guarantee you'll get anything. Context, leverage, motivations - always gotta consider those. This advice is very good in the relevant contexts.
