All bets are off if you have even minimal "fuck you" money, of course.
Most people don't, though. They can't go long without a job, and having a gap on their résumé is scary (for good reason—if you need a job, anything that might make getting the next one a little harder isn't good).
As a candidate just another question to worry about, even if it doesn't actually come up, and at best the result of it coming up is neutral, not positive for you. The more you need the job, the more stressful that sort of thing is.
