No, the issue is a systemic one. Education access, job market, housing and living costs, mean that low-qualification, low-pay jobs are the only option for a lot of people. And when that pay is below minimum wage unless you take additional risks upsetting people, where does the personal responsibility actually lie? Did OP fail their personal responsibility because a customer was upset? Or did they succeed in being responsible because taking those risks is necessary to make rent and afford groceries, pay for insurance, etc? When you take into account the challenges and complexities of the distribution of these costs, the real holders of responsibility, and the way in which all the odds are stacked against the worker in the lowest position on the social ladder, all of your arguments break down.
