This film showed frequently in mid-1980’s HBO. A Gene Wilder-type white guy experiences a series of mishaps in which he has to experience life in the ghetto or just working-life. I think it may have had a black-white buddy theme or just a rich white guy learning the reality of becoming poor. One scene I vividly remember was the exasperated hero sitting down on an unattached toilet seat he has been carrying around with him through his terrible day for a moment’s relief. He may have worked as a construction worker.
