Counter counterpoint: I accepted a counter offer. Turns out my boss was literally lying about the counter offer. Raise never showed up in my paycheck despite my repeated bringing up the issue, and the repeated assurance it was just a payroll issue. The original job offer was no longer good, they'd hired someone else, so I spent another few months looking for a job. When I quit the second time around (boss had been fired for this, by the way) the company owner had the nerve the offer me the backpay I was owed if only I'd just reconsider quitting.

The lawsuit is still ongoing. :)
